[PATCH 2/2] platform/x86: wmi: Avoid returning AE_OK upon unknown error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


If an error code other than EINVAL, ENODEV or ETIME is returned
by ec_read()/ec_write(), then AE_OK is wrongly returned.

Fix this by only returning AE_OK if the return code is 0, and
return AE_ERROR otherwise.

Tested on a Dell Inspiron 3505 and a Asus Prime B650-Plus.
