[PATCH V3 3/6] brcmfmac: fix the incorrect return value in brcmf_inform_single_bss().

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

 



From: Raveendran Somu <raveendran.somu@xxxxxxxxxxx>

The function brcmf_inform_single_bss returns the value as success,
even when the length exceeds the maximum value.
The fix is to send appropriate code on this error.
This issue is observed when Cypress test group reported random fmac
crashes when running their tests and the path was identified from the
crash logs. With this fix the random failure issue in Cypress test group
was resolved.
