From: Adham Abozaeid <[email protected]>
Validate input parameters to set_wiphy_param before scheduling
handle_cfg_param() to validate them.
This way proper errors can be returned to caller.
Also cleaned up unused code in handle_cfg_param.
Changes since v1:
- Correction spelling in subject of patch#2
- Added From: tag to have correct email from value
Changes since v2:
- Reverted unnecessary file permission changes
Adham Abozaeid (4):
staging: wilc1000: remove unused flags in handle_cfg_param()
staging: wilc1000: validate cfg parameters before scheduling the work
staging: wilc1000: Don't keep a copy of wiphy parameters in the driver
staging: wilc1000: Remove unused mutex cfg_values_lock

Please fix this up so that the 0-day bot does not complain about it.

Sure Greg. I'll submit v4 with the fix for the bot warning.
I assume I shouldn't include patch 1/4 in the new version of the series since I see it was applied already, so I'll only resend the other 3 patches
Thanks,
Adham
