[PATCH] staging: wilc1000: Update handler assignment logic

Aditya Shankar aditya.shankar at microchip.com
Fri Apr 7 11:54:05 UTC 2017


With this update, the host driver is consistent with the
implementation on the firmware side with respect to obtaining
the driver handler for all modes.
With this new format, the calls to set the wilc operation mode
is simplified.
