[Linux-stable-mirror] [PATCH 4.9.y] ASoC: simple-card: Fix misleading error message

[Linux-stable-mirror] [PATCH 4.4.y] drm: rcar-du: Fix race condition when disabling planes at CRTC stop

by Nhan Nguyen

From: thongsyho <thong.ho.px(a)rvc.renesas.com> commit 641307df71fe77d7b38a477067495ede05d47295 upstream. When stopping the CRTC the driver must disable all planes and wait for the change to take effect at the next vblank. Merely calling drm_crtc_wait_one_vblank() is not enough, as the function doesn't include any mechanism to handle the race with vblank interrupts. Replace the drm_crtc_wait_one_vblank() call with a manual mechanism that handles the vblank interrupt race.

[Linux-stable-mirror] [PATCH 4.4.y] drm: rcar-du: Use the VBK interrupt for vblank events

When implementing support for interlaced modes, the driver switched from reporting vblank events on the vertical blanking (VBK) interrupt to the frame end interrupt (FRM).

From: thongsyho <thong.ho.px(a)rvc.renesas.com> commit 1f8754d4daea5f257370a52a30fcb22798c54516 upstream. If SSI uses shared pin, some SSI will be used as parent SSI.

[Linux-stable-mirror] [PATCH] MIPS: CPS: Fix MIPS_ISA_LEVEL_RAW fallout

by James Hogan

Commit 17278a91e04f ("MIPS: CPS: Fix r1 .set mt assembler warning") added .set MIPS_ISA_LEVEL_RAW to silence warnings about .set mt on r1, however this can result in a MOVE being encoded as a 64-bit DADDU instruction on certain version of binutils (e.g. 2.22), and reserved instruction exceptions at runtime on 32-bit hardware. Reduce the sizes of the push/pop sections to include only instructions that are part of the MT ASE or which won't convert to 64-bit instructions after .set mips64r2/mips64r6.
