From 3eda901995371d390ef82d0b6462f4ea8efbcfdf Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 1 Oct 2021 15:59:04 +0300 Subject: [PATCH] drm/msm/a3xx: fix error handling in a3xx_gpu_init() These error paths returned 1 on failure, instead of a negative error code. This would lead to an Oops in the caller. A second problem is that the check for "if (ret != -ENODATA)" did not work because "ret" was set to 1.
