Implement unlocked variants of v4l2_ctrl_s_ctrl() and v4l2_ctrl_s_ctrl_int64(). As drivers need to set controls as they access driver internal state elsewhere than in the control framework unlocked variants of these functions become handy. Signed-off-by:

Drivers may use the v4l2_ctrl_modify_range() internally as part of other operations that need to be both serialised using a driver's lock which can also be used to serialise access to the control handler. Provide an unlocked version of the function, __v4l2_ctrl_modify_range() which then may be used by drivers for the purpose. Signed-off-by:

OVL and BTP IRAM buffers are never used, setup the bits for for DBK/BIT/IP usage depending on CODA version in one place. Also, use a simple allocator function and group IRAM addresses and size in a coda_aux_buf structure. This is done in preparation for CODA960 support. Signed-off-by:

Philipp Zabel authored
Currently the rotator unit is used to copy decoded frames out into buffers provided by videobuf2. Since the CODA reports the I/P/B frame type of the last decoded frame, and this frame will be copied out in a later device_run, depending on display order, we have to store the frame type until such time. This patch also adds the B-frame type. Signed-off-by:

fc906b6d "Remove special clock usage in driver" removed initialization of MFC special clock, arguing that there's no need to do it explicitly, since it's one of MFC gate clock's dependencies and gets enabled along with it. However, there's no promise of keeping this hierarchy across Exynos SoC releases, therefore this approach fails to provide a stable, portable solution. Out of all MFC versions, only v6 doesn't use special clock at all. For other versions log a message only in case clk_get fails, as not all the devices with the same MFC version require initializing the clock explicitly. Signed-off-by:

In the s5p_mfc_alloc_firmware() function there are some mistakes where the code checks whether the DMA memory is properly allocated or not. First of all dma_alloc_coherent() returns NULL in case of error. The code also checked two times fw_virt_addr, ignoring the bank2_virt pointer. Signed-off-by:

This patch removes the null test on dvb. dvb is initialized at the beginning of the function to &port->dvb. Since port is dereferenced prior to the null test, port must be a valid pointer, and &port->dvb cannot be null. The following Coccinelle script is used for detecting the change: @r@ expression e,f; identifier g,y; statement S1,S2; @@ *e = &f->g <+... f->y ...+> *if (e != NULL || ...) S1 else S2 Signed-off-by:

The issue was discovered by static analysis. It turns out that code is somewhat insane, being if (x) {...} else { if (x) {...} } Edited it to do the only reasonable thing, which is to log the information about the failed call. The most descriptive logging commands set is taken from original code. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=79801Reported-by:Mike Isely <isely@pobox.com> Signed-off-by:
