2020-08-23treewide: Use fallthrough pseudo-keywordGustavo A. R. Silva
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2020-07-20video: fbdev: Replace HTTP links with HTTPS onesAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2019-12-05video: constify fb ops across all driversJani Nikula
Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

The cpufreq policy notifier's CPUFREQ_ADJUST notification is going to get removed soon. The notifier callback sa1100fb_freq_policy() isn't doing anything apart from printing a debug message on CPUFREQ_ADJUST notification. There is no point in keeping an otherwise empty callback and registering the notifier. Remove it.

2016-03-09dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()Luis R. Rodriguez
Rename dma_*_writecombine() to dma_*_wc(), so that the naming is coherent across the various write-combining APIs. Keep the old names for compatibility for a while, these can be removed at a later time. A guard is left to enable backporting of the rename, and later remove of the old mapping defines seemlessly. Build tested successfully with allmodconfig. The following Coccinelle SmPL patch was used for this simple transformation: @ rename_dma_alloc_writecombine @ expression dev, size, dma_addr, gfp; @@ -dma_alloc_writecombine(dev, size, dma_addr, gfp) +dma_alloc_wc(dev, size, dma_addr, gfp) @ rename_dma_free_writecombine @ expression dev, size, cpu_addr, dma_addr; @@ -dma_free_writecombine(dev, size, cpu_addr, dma_addr) +dma_free_wc(dev, size, cpu_addr, dma_addr) @ rename_dma_mmap_writecombine @ expression dev, vma, cpu_addr, dma_addr, size; @@ -dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size) +dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size) We also keep the old names as compatibility helpers, and guard against their definition to make backporting easier.

2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
