[PATCH] fbdev: sm712fb: set error code in probe
by Evgeny Novikov 10 Jul '20

If smtcfb_pci_probe() does not detect a valid chip it cleans up everything and returns 0. This can result in various bad things later. The patch sets the error code on the corresponding path.

[PATCH] fbdev: da8xx-fb: go to proper label on error handling paths in probe
by Evgeny Novikov 10 Jul '20

10 Jul '20

fb_probe() can successfully allocate a new frame buffer, but then fail to perform some operations with regulator. In these cases fb_probe() goes to label err_pm_runtime_disable where the frame buffer is not released. The patch makes fb_probe() to go to label err_release_fb on corresponding error handling paths.

[PATCH] omapfb: dss: Fix max fclk divider for omap36xx
by Adam Ford 10 Jul '20

10 Jul '20

The drm/omap driver was fixed to correct an issue where using a divider of 32 breaks the DSS despite the TRM stating 32 is a valid number. Through experimentation, it appears that 31 works, and it is consistent with the value used by the drm/omap driver. This patch fixes the divider for fbdev driver instead of the drm.

[PATCH] video: fbdev: neofb: fix memory leak in neo_scan_monitor()
by Evgeny Novikov 10 Jul '20

10 Jul '20

neofb_probe() calls neo_scan_monitor() that can successfully allocate a memory for info->monspecs.modedb and proceed to case 0x03. There it does not free the memory and returns -1. neofb_probe() goes to label err_scan_monitor, thus, it does not free this memory through calling fb_destroy_modedb() as well. We can not go to label err_init_hw since neo_scan_monitor() can fail during memory allocation. So, the patch frees the memory directly for case 0x03.
