Subject: drm/i915: Silence __iomem sparse warn
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 6b9376504cb486ffdf93ee1a98c5ce0d02699857
Patch-mainline: v5.16-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
We don't care about __iomem mismatch when dealing with error
pointers. Silence it with ERR_CAST().
drivers/gpu/drm/i915/display/intel_dpt.c:136:21: warning: incorrect type in assignment (different address spaces)
drivers/gpu/drm/i915/display/intel_dpt.c:136:21: expected struct i915_vma *[assigned] vma
drivers/gpu/drm/i915/display/intel_dpt.c:136:21: got void [noderef] __iomem *[assigned] iomem
v2: The code moved into intel_dpt.c
