video: fbdev: sstfb: Updated logging to fix set but not used warnings

2020-11-30T19:04:59Z

Fix set but not used warnings by introducing no_printk variants for the internal logging system for this driver. Fix a new warning that popped up now that logging was checked for correct printf format strings. A more invasive fix had been to replace all the internal logging with standard logging primitives - thats for another day. v2: - Update subject (Lee) Signed-off-by: Sam Ravnborg Acked-by: Thomas Zimmermann Cc: Sam Ravnborg Cc: Daniel Vetter Cc: Arnd Bergmann Cc: Bartlomiej Zolnierkiewicz Cc: Alex Dewar Cc: Jani Nikula Cc: linux-fbdev@vger.kernel.org Cc: Lee Jones Link: https://patchwork.freedesktop.org/patch/msgid/20201128224114.1033617-20-sam@ravnborg.org

fbdev: remove mbx framebuffer driver

2020-09-08T11:33:32Z

The only in-tree user for mbx driver for Intel 2700G graphics chip was cm-x270 platform. Since this platform was removed by the commit 9d3239147d6d ("ARM: pxa: remove Compulab pxa2xx boards") there is no point to keep the obsolete framebuffer driver.

video: Replace zero-length array with flexible-array member

2020-03-02T15:32:17Z

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

video: exynos: Rename Exynos to lowercase

2020-01-15T16:31:51Z

Fix up inconsistent usage of upper and lowercase letters in "Exynos" name. "EXYNOS" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website.

Rename picture parameter set (it's a long packet, not a long write) and compression mode (it's not a DCS command) enumerations according to the DSI specification. Order the types according to the spec. Use tabs instead of spaces for indentation. Use all lower case for hex.
