Subject: [PATCH] drm/i915/gt: Reduce log severity on reset prepare.
Date: Fri,  1 Dec 2023 16:44:43 +0100	[thread overview]
Message-ID: <20231201154443.16660-1-nirmoy.das@intel.com> (raw)

gen8_engine_reset_prepare() can fail when HW fails to set
RESET_CTL_READY_TO_RESET bit. In some cases this is not fatal
error as driver will retry.

Let the caller of gen8_engine_reset_prepare() decide if a
failure in gen8_engine_reset_prepare is an error or not.
