Subject: [PATCH] staging: rtl8723bs: Fix the return value in case of error in 'rtw_wx_read32()'
Git-commit: c3e43d8b958bd6849817393483e805d8638a8ab7
Patch-mainline: 4.20-rc5
References: bsc#1051510
We return 0 unconditionally in 'rtw_wx_read32()'.
However, 'ret' is set to some error codes in several error handling paths.
Return 'ret' instead to propagate the error code.
Fixes: 554c0a3abf216 ("staging: Add rtl8723bs sdio wifi driver")
