Subject: staging: wilc1000: remove pstrWFIDrv in host_int_set_mac_chnl_num
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=157da215b5312017889dc856e770c422db336aac;p=deliverable%2Flinux.git

staging: wilc1000: remove pstrWFIDrv in host_int_set_mac_chnl_num

This patch removes pstrWFIDrv variable in host_int_set_mac_chnl_num
function. There is no need to make another variable to check if first
arugment is NULL or not.
It is able to use wfi_drv directly that is first argument of
this function.
