Subject: [PATCH] rsi: fix error return code of rsi_load_9116_firmware()
Date: Sun, 7 Mar 2021 00:34:45 -0800 [thread overview]
Message-ID: <20210307083445.21322-1-baijiaju1990@gmail.com> (raw)
When kmemdup() returns NULL to ta_firmware, no error return code of
rsi_load_9116_firmware() is assigned.
To fix this bug, status is assigned with -ENOMEM in this case.
