staging: rtl8188eu: remove dead code in rtw_drv_init()
(status != _SUCCESS) immediately after 'status = _SUCCESS' will never evaluate
true. Thus remove the logically dead code. Detected by Coverity - CID 1077553.
staging: rtl8188eu: fix usage of uninit scalar in rtw_drv_init()
Function rtw_drv_init() is written in a way that assumes 'status' != _SUCCESS
as long as not explicitly set. Thus initialize 'status' to FAIL, in order to
prevent undefined behaviour if going through the exit paths. Detected by
Coverity - CID 1077832.
staging: rtl8188eu: fix potential leak in rtw_set_key()
Fix a potential leak in the error path of rtw_set_key(). In case the requested
algorithm is not supported by the driver, the function returns without
enqueuing or freeing the already allocated command and parameter structs. Use
a centralized exit path and make sure that all memory is freed correctly.
Detected by Coverity - CID 1077716, 1077717.
