[PATCH 07/10] staging: rtl8712: init_drv_sw(): Change return values

Thu Aug 8 06:40:09 UTC 2019


Change return values of init_drv_sw from _SUCCESS and _FAIL to 0 and
-ENOMEM. Change return type from u8 to int to allow this.
Add a return variable to streamline return of error codes of called
functions.
Modify call site to check for non-zero return value instead of _FAIL.
