Subject: [PATCH 1/2] staging: r8188eu: fix memory leak in rtw_set_key
Date: Fri,  3 Sep 2021 21:17:52 +0300	[thread overview]
Message-ID: <ee783fbb71abb549505b84542223be7a7c905eea.1630692375.git.paskripkin@gmail.com> (raw)

Before returning with an error we should free allocated buffers, since
they are not assigned to anywhere.

Fixes: 15865124feed ("staging: r8188eu: introduce new core dir for RTL8188eu driver")
