fbdev: amifb: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper

2023-07-31T12:54:08+00:00

Replacing zero-length arrays with C99 flexible-array members because they are deprecated. Use the new DECLARE_FLEX_ARRAY() auxiliary macro instead of defining a zero-length array. This fixes warnings such as: ./drivers/video/fbdev/amifb.c:690:6-10: WARNING use flexible-array member instead Signed-off-by: Atul Raut Signed-off-by: Helge Deller

fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs

2023-07-24T14:50:38+00:00

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by framebuffer_alloc(). So do not set it. Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed. v4: * clarify commit message (Geert, Dan) v2: * fix commit message (Miguel) Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Cc: Helge Deller Cc: Nicolas Ferre Cc: Benjamin Herrenschmidt Cc: Ferenc Bakonyi Cc: "K.

video: fbdev: amiga: Simplify amifb_pan_display()

2022-07-18T05:54:17+00:00

The fb_pan_display() function in the core already takes care of validating most panning parameters before calling the driver's .fb_pan_display() callback, and of updating the panning state afterwards, so there is no need to repeat that in the driver. Remove the duplicate code. Signed-off-by: Geert Uytterhoeven Signed-off-by: Helge Deller

Since we lack the hardware (or proper emulator setup) for testing needed changes add FIXMEs to document the issues (so at least they are not forgotten).

video: constify fb ops across all drivers

2019-12-05T08:57:53+00:00

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 Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

video: fbdev: don't print error message on framebuffer_alloc() failure

2019-06-28T10:30:08+00:00

framebuffer_alloc() can fail only on kzalloc() memory allocation failure and since kzalloc() will print error message in such case we can omit printing extra error message in drivers (which BTW is what the majority of framebuffer_alloc() users is doing already).
