From 242443430dd8ef932a56cf483080a46f2948dd65 Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Tue, 25 Oct 2022 11:12:25 +0200 Subject: [PATCH] staging: rtl8712: check for return value of _r8712_init_xmit_priv() The return value of _r8712_init_xmit_priv() is never checked and the driver always continue execution as if all is well. This will cause problems if, for example, buffers cannot be allocated and the driver continue and use those buffers. Check for return value of _r8712_init_xmit_priv() and return error (if any) during probing.
