Subject: [PATCH] drm/msm/dpu: Fix error return code in dpu_mdss_init()
Date: Tue, 17 Nov 2020 10:56:17 +0800	[thread overview]
Message-ID: <20201117025617.168259-1-chenzhou10@huawei.com> (raw)

Fix to return a negative error code from the error handling case
instead of 0 in function dpu_mdss_init(), as done elsewhere in this
function.

Fixes: 070e64dc1bbc ("drm/msm/dpu: Convert to a chained irq chip")
