In function via_mem_alloc`s error branch, DRM_ERROR is protected in the mutex_lock(&dev->struct_mutex) area. >From the code, we see that DRM_ERROR is just an error log print without any struct element, there is no need to protect this. Signed-off-by:

On some panels hooked up to the ti-sn65dsi86 bridge chip we found that link training was failing. Specifically, we'd see: ti_sn65dsi86 2-002d: [drm:ti_sn_bridge_enable] *ERROR* Link training failed, link is off (-5) The panel was hooked up to a logic analyzer and it was found that, as part of link training, the bridge chip was writing a 0x1 to DPCD address 00600h and the panel responded NACK. As can be seen in header files, the write of 0x1 to DPCD address 0x600h means we were trying to write the value DP_SET_POWER_D0 to the register DP_SET_POWER. The panel vendor says that a NACK in this case is not unexpected and means "not ready, try again". In testing, we found that this panel would respond with a NACK in about 1/25 times. Adding the retry logic worked fine and the most number of tries needed was 3. Just to be safe, we'll add 10 tries here and we'll add a little blurb to the logs if we ever need more than 5.

Guido Günther authored
The mantix panel needs two reset lines (RESX and TP_RSTN) deasserted to output an image. Only deasserting RESX is not enough and the display will stay blank. Deassert in prepare() and assert in unprepare() to keep device held in reset when off. Signed-off-by:

Inspired by a patch by Chris Wilson for vgem. Plus this gives us vmap at the gem bo level, which we need for generic fbdev emulation. Luckily shmem also tracks ->vaddr, so we just need to adjust the code all over a bit to make this fit. Also wire up handle_to_fd, dunno why that was missing. v2: - Drop now unused container_of #define (Melissa) - Make sure we keep creating cached objects, this is for testing (Thomas) Signed-off-by:
