2020-01-15pxa168fb: fix release function mismatch in probe failureChuhong Yuan1-1/+1
The driver uses kfree() to release the resource allocated by framebuffer_alloc(), which does not match. Use framebuffer_release() instead to fix it.

2020-01-03pxa168fb: Fix the function used to release some memory in an error handling pathChristophe JAILLET1-3/+3
In the probe function, some resources are allocated using 'dma_alloc_wc()', they should be released with 'dma_free_wc()', not 'dma_free_coherent()'. We already use 'dma_free_wc()' in the remove function, but not in the error handling path of the probe function. Also, remove a useless 'PAGE_ALIGN()'. 'info->fix.smem_len' is already PAGE_ALIGNed.

2019-12-05video: constify fb ops across all driversJani Nikula1-1/+1
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

2016-03-09dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()Luis R. Rodriguez1-4/+4
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.

2015-09-01video: fbdev: pxa168fb: Use devm_clk_getVaishali Thakkar1-10/+4
This patch introduces the use of managed resource function devm_clk_get instead of clk_get and removes corresponding calls to clk_put in the probe and remove functions. To be compatible with the change various gotos are replaced with direct returns, and unneeded label failed_put_clk is dropped.

2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-0/+837
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.
