Instead of a big if at the beginning, just check if g_selection == NULL and call the cropcap op immediately and return the result. No functional changes in this patch. Signed-off-by:

Hans Verkuil authored
Instead of letting drivers fill in device_caps at querycap time, let them fill it in when the video device is registered. This has the advantage that in the future the v4l2 core can access the video device's capabilities and take decisions based on that. Signed-off-by:

The MIPI CSIS DT parse function return an -ENXIO errno if the port # is outside of the supported values. But it doesn't call of_node_put() to decrement the node's reference counter, that's incremented inside the of_graph_get_next_endpoint() function that was called before. Instead of just returning, go to the error path that already does it. Signed-off-by:

In commit e4570897 ("drm/dp-helper: Move the legacy helpers to gma500") the legacy i2c helpers were moved to the only remaining user of them, the gma500 driver. Together with that move, i2c_dp_aux_add_bus() was marked deprecated and started warning about its remaining use. It's now been a year and a half of annoying warning, and apparently nobody cares enough about gma500 to try to move it along to the more modern models. Get rid of the warning - if even the gma500 people don't care enough, then they should certainly not spam other innocent developers with a warning that might hide other, much more real issues.

Merge PAGE_CACHE_SIZE removal patches from Kirill Shutemov: "PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE. This promise never materialized. And unlikely will. Let's stop pretending that pages in page cache are special. They are not. The first patch with most changes has been done with coccinelle. The second is manual fixups on top. The third patch removes macros definition" [ I was planning to apply this just before rc2, but then I spaced out, so here it is right _after_ rc2 instead. As Kirill suggested as a possibility, I could have decided to only merge the first two patches, and leave the old interfaces for compatibility, but I'd rather get it all done and any out-of-tree modules and patches can trivially do the converstion while still also working with older kernels, so there is little reason to try to maintain the redundant legacy model. - Linus ] * PAGE_CACHE_SIZE-removal: mm: drop PAGE_CACHE_* and page_cache_{get,release} definition mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros -

PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE. This promise never materialized. And unlikely will. We have many places where PAGE_CACHE_SIZE assumed to be equal to PAGE_SIZE. And it's constant source of confusion on whether PAGE_CACHE_* or PAGE_* constant should be used in a particular case, especially on the border between fs and mm. Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much breakage to be doable. Let's stop pretending that pages in page cache are special. They are not. The changes are pretty straight-forward: - <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN}; - page_cache_get() -> get_page(); - page_cache_release() -> put_page(); This patch contains automated changes generated with coccinelle using script below. For some reason, coccinelle doesn't patch header files. I've called spatch for them manually. The only adjustment after coccinelle is revert of changes to PAGE_CAHCE_ALIGN definition: we are going to drop it later. There are few places in the code where coccinelle didn't reach. I'll fix them manually in a separate patch. Comments and documentation also will be addressed with the separate patch. virtual patch @@ expression E; @@ - E << (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ expression E; @@ - E >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ @@ - PAGE_CACHE_SHIFT + PAGE_SHIFT @@ @@ - PAGE_CACHE_SIZE + PAGE_SIZE @@ @@ - PAGE_CACHE_MASK + PAGE_MASK @@ expression E; @@ - PAGE_CACHE_ALIGN(E) + PAGE_ALIGN(E) @@ expression E; @@ - page_cache_get(E) + get_page(E) @@ expression E; @@ - page_cache_release(E) + put_page(E) Signed-off-by: -

Make sure it's the microMIPS rather than MIPS16 ISA before emulating microMIPS RDHWR. Mostly needed as an optimisation for configurations where `cpu_has_mmips' is hardcoded to 0 and also a good measure in case we add further microMIPS instructions to emulate in the future, as the corresponding MIPS16 encoding is ADDIUSP, not supposed to trap.

Moving an unmasked irq may result in irq handler being invoked on both source and target CPUs. With 2-level this can happen as follows: On source CPU: evtchn_2l_handle_events() -> generic_handle_irq() -> handle_edge_irq() -> eoi_pirq(): irq_move_irq(data); /***** WE ARE HERE *****/ if (VALID_EVTCHN(evtchn)) clear_evtchn(evtchn); If at this moment target processor is handling an unrelated event in evtchn_2l_handle_events()'s loop it may pick up our event since target's cpu_evtchn_mask claims that this event belongs to it *and* the event is unmasked and still pending. At the same time, source CPU will continue executing its own handle_edge_irq(). With FIFO interrupt the scenario is similar: irq_move_irq() may result in a EVTCHNOP_unmask hypercall which, in turn, may make the event pending on the target CPU. We can avoid this situation by moving and clearing the event while keeping event masked. Signed-off-by:

When an unsupported reloc is encountered in a module, we currently blindly branch to whatever would be at its entry in the reloc handler function pointer arrays. This may be NULL, or if the unsupported reloc has a type greater than that of the supported reloc with the highest type then we'll dereference some value after the function pointer array & branch to that. The result is at best a kernel oops. Fix this by checking that the reloc type has an entry in the function pointer array (ie. is less than the number of items in the array) and that the handler is non-NULL, returning an error code to fail the module load if no handler is found.

Current ath79 clock.c code does not read reference clock and pll setup from devicetree. The ar724x_clocks_init() function recreates the clocks from scratch so devicetree clock information is dropped. After adding the code which picked up reference clock from devicetree I have found that kernel does not boot anymore. The SPI and UART drivers can't get clk; here are the bootlog error messages: of_serial: probe of 18020000.uart failed with error -22 ath79-spi: probe of 1f000000.spi failed with error -22 The problem is that clock code assumes that reference clock name is "ref" but current dts-file uses another name: "oscillator". This patch fixes the problem by changing external oscillator dt node name to "ref".

The reference clock on ar913x is at 40MHz and not 5MHz. The current implementation use the wrong reference rate because it doesn't take the PLL divider in account. But if we fix the code to use the divider it becomes identical with the implementation for ar724x, so just drop the broken ar913x implementation. Signed-off-by:
