+Subject: drm/amd/pm: conditionally disable pcie lane switching for some sienna_cichlid SKUs
+
+From: Evan Quan <evan.quan@amd.com>
+
+commit 38e4ced804796c5725e2a52ec3601951552c4a97 upstream.
+
+Disable the pcie lane switching for some sienna_cichlid SKUs since it
+might not work well on some platforms.

+Subject: drm/amdgpu: fix xclk freq on CHIP_STONEY
+
+From: Chia-I Wu <olvaffe@gmail.com>
+
+commit b447b079cf3a9971ea4d31301e673f49612ccc18 upstream.
+
+According to Alex, most APUs from that time seem to have the same issue
+(vbios says 48Mhz, actual is 100Mhz). I only have a CHIP_STONEY so I
+limit the fixup to CHIP_STONEY

+Subject: drm/i915/gt: Use the correct error value when kernel_context() fails
+
+From: Andi Shyti <andi.shyti@linux.intel.com>
+
+commit 40023959dbab3c6ad56fa7213770e63d197b69fb upstream.
+
+kernel_context() returns an error pointer. Use pointer-error
+conversion functions to evaluate its return value, rather than
+checking for a '0' return.
