Subject: [PATCH] drm/xe/device: clean up on error in probe()
Date: Fri, 5 Jan 2024 15:22:23 +0300	[thread overview]
Message-ID: <c8984fe2-dc1a-4ba8-97c9-5c83f53a0d09@moroto.mountain> (raw)

This error path should clean up before returning.

Smatch detected this bug:
  drivers/gpu/drm/xe/xe_device.c:487 xe_device_probe() warn: missing unwind goto?

Fixes: 4cb12b71923b ("drm/xe/xe2: Determine bios enablement for flat ccs on igfx")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
---
Speeking of static analysis, someone should probably run Sparse on this
driver.  There are some missing annotations.
