The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here).

The register abstraction has wrappers around both the normal writel() and its writel_relaxed() counterpart, but this has led to a lot of users ending up with the relaxed version. There is sometimes a need to intentionally pick the relaxed accessor for performance critical functions, but I noticed that each hantro_reg_write() call also contains a non-relaxed readl(), which is typically much more expensive than a writel, so there is little benefit here but an added risk of missing a serialization against DMA. To make this behave like other interfaces, use the normal accessor by default and only provide the relaxed version as an alternative for performance critical code. hantro_postproc.c is the only place that used both the relaxed and normal writel, but this does not seem cricital either, so change it all to the normal ones.

In some configurations, gcc decides not to inline the register accessor functions, which in turn leads to lots of temporary hantro_reg structures on the stack that cannot be eliminated because they escape into an uninlined function: drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c:1022:1: warning: the frame size of 1112 bytes is larger than 1024 bytes [-Wframe-larger-than=] Mark all of these as __always_inline so the compiler is able to completely eliminate the temporary structures instead, which brings the stack usage back down to just the normal local variables.

The mtk8195_jpegenc_drvdata object was added outside of an #ifdef causing a harmless build warning. drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.c:1879:32: error: 'mtk8195_jpegenc_drvdata' defined but not used [-Werror=unused-variable] 1879 | static struct mtk_jpeg_variant mtk8195_jpegenc_drvdata = { | ^~~~~~~~~~~~~~~~~~~~~~~ A follow-up patch moved it inside of an #ifdef, which caused more warnings, and a third patch ended up adding even more #ifdefs. These were all bogus, since the actual problem here is the incorrect use of of_ptr(). Since the driver (like any other modern platform driver) only works in combination with CONFIG_OF, there is no point in hiding the reference, so just remove that along with all the pointless #ifdef checks in the driver. This improves build coverage and avoids running into the same problem again when another part of the driver gets changed that relies on the #ifdef blocks to be completely matched.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair. Repeats: 80e62bc8 ("MAINTAINERS: re-sort all entries and fields") Signed-off-by:
