Zero-length arrays are deprecated[1] and are being replaced with flexible array members in support of the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy(), correctly instrument array indexing with UBSAN_BOUNDS, and to globally enable -fstrict-flex-arrays=3. Replace zero-length array with flexible-array member. This results in no differences in binary output.

The current CLRSIPO count is still marginal and does not work with high DSI clock rates in burst mode. Increase it further to allow the DSI link to work at up to 1Gbps lane speed.

Include <linux/of.h> in source files that need it. Some of DRM's source code gets OF header via drm_crtc_helper.h and <linux/fb.h>, which can leed to unnecessary recompilation. In drm_modes.c, add a comment on the reason for still including <linux/fb.h>. The header file is required to get KHZ2PICOS(). The macro is part of the UAPI headers, so it cannot be moved to a less prominent location. v2: * include <linux/of.h> in komeda_drv.c (kernel test robot) Signed-off-by:

This reverts commit ae128786. Always free the console font when deinitializing the framebuffer console. Subsequent framebuffer consoles will then use the default font. Rely on userspace to load any user-configured font for these consoles. Commit ae128786 ("fbcon: don't lose the console font across generic->chip driver switch") was introduced to work around losing the font during graphics-device handover. [1][2] It kept a dangling pointer with the font data between loading the two consoles, which is fairly adventurous hack. It also never covered cases when the other consoles, such as VGA text mode, where involved. The problem has meanwhile been solved in userspace. Systemd comes with a udev rule that re-installs the configured font when a console comes up. [3] So the kernel workaround can be removed. This also removes one of the two special cases triggered by setting FBINFO_MISC_FIRMWARE in an fbdev driver. Tested during device handover from efifb and simpledrm to radeon. Udev reloads the configured console font for the new driver's terminal. Signed-off-by:
