[PATCH] drm/mediatek: fix implicit function declaration

When building mtk_drm_drv.o the following build error is seen: ../drivers/gpu/drm/mediatek/mtk_drm_drv.c: In function ‘mtk_drm_kms_init’: ../drivers/gpu/drm/mediatek/mtk_drm_drv.c:291:8: error: implicit declaration of function ‘dma_set_max_seg_size’; did you mean ‘drm_rect_adjust_size’?

[PATCH for v5.3] cec-adap: return from cec_s_conn_info() if adap is invalid
by Hans Verkuil 23 Aug '19

Check if cec_s_conn_info is called with a valid cec adapter, do nothing if it is invalid. This makes it possible to call this function even if CEC support is disabled in the kernel config.

[PATCH] drm/komeda: Reordered the komeda's de-init functions
by Ayan Halder 23 Aug '19

23 Aug '19

The de-init routine should be doing the following in order:- 1. Unregister the drm device 2. Shut down the crtcs - failing to do this might cause a connector leakage See the 'commit 109c4d18e574 ("drm/arm/malidp: Ensure that the crtcs are shutdown before removing any encoder/connector")' 3. Disable the interrupts 4. Unbind the components 5.

Hello Steven Price, This is a semi-automatic email about new static checker warnings.

[PATCH 0/4] mmu notifier debug annotations/checks
by Daniel Vetter 23 Aug '19

23 Aug '19

Hi all, Here's the respin. Changes: - 2 patches for checking return values of callbacks dropped, they landed - move the lockdep annotations ahead, since I think that part is less contentious. lockdep map now also annotates invalidate_range_end, as requested by Jason. - add a patch to prime lockdep, idea from Jason, let's hear whether the implementation fits. - I've stuck with the non_block_start/end for now and not switched back to preempt_disable/enable, but with comments as suggested by Andrew. Hopefully that fits the bill, otherwise I can go back again if the consensus is more there. Review, comments and ideas very much welcome.

[PATCH] drm/omap: Fix port lookup for SDI output
by Laurent Pinchart 23 Aug '19

23 Aug '19

When refactoring port lookup for DSS outputs, commit d17eb4537a7e ("drm/omap: Factor out common init/cleanup code for output devices") incorrectly hardcoded usage of DT port 0. This breaks operation for SDI (which uses the DT port 1) and DPI outputs other than DPI0 (which are not used in mainline DT sources). Fix this by using the port number from the output omap_dss_device of_ports field.
