git://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux Pull Hyper-V fixes from Wei Liu: "One fix from Lu Yunlong for a double free in hvfb_probe" * tag 'hyperv-fixes-signed-20210402' of git://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux: video: hyperv_fb: Fix a double free in hvfb_probe
2021-03-25video: hyperv_fb: Fix a double free in hvfb_probeLv Yunlong1-3/+0
Function hvfb_probe() calls hvfb_getmem(), expecting upon return that info->apertures is either NULL or points to memory that should be freed by framebuffer_release(). But hvfb_getmem() is freeing the memory and leaving the pointer non-NULL, resulting in a double free if an error occurs or later if hvfb_remove() is called. Fix this by removing all kfree(info->apertures) calls in hvfb_getmem(). This will allow framebuffer_release() to free the memory, which follows the pattern of other fbdev drivers.

Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

2021-02-01ARM: 9049/1: locomo: make locomo bus's remove callback return voidUwe Kleine-König1-2/+1
The driver core ignores the return value of struct bus_type::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct locomo_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

mutually exclusive Standard DRM panel driver for DSI command mode panel used by omapfb2 is also available now. Just like the other panels its module name clashes with the module from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver is disabled, and the DRM panel drivers are useless in that case, make the omapfb2 panel depend on the standard DRM panels being disabled to fix the name clash.

So the check for BROKEN_GRAPHICS_PROGRAMS is pointless in vgacon.c as it is always true. So remove the test and BROKEN_GRAPHICS_PROGRAMS completely.

2020-12-03powerpc/ps3: make system bus's remove and shutdown callbacks return voidUwe Kleine-König1-3/+1
The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. For the shutdown callback it's ps3_system_bus_shutdown() which ignores the return value. To simplify the quest to make struct device_driver::remove return void, let struct ps3_system_bus_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

2020-11-30video: fbdev: sstfb: Updated logging to fix set but not used warningsSam Ravnborg1-1/+1
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 <sam@ravnborg.org> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Cc: Alex Dewar <alex.dewar90@gmail.com> Cc: Jani Nikula <jani.nikula@intel.com> Cc: linux-fbdev@vger.kernel.org Cc: Lee Jones <lee.jones@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201128224114.1033617-20-sam@ravnborg.org
