Subject: at86rf230: fix page parameter constraints
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fe23bcd920015bfb655f4b3d129a9368ce8e660c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

at86rf230: fix page parameter constraints

Since commit e37d2ec82a222f1819e7793a27bc052999a379fb ("mac802154: ops:
declare channel and page as u8") the page parameter can't be below zero.
This patch fix a kbuild test robot warning. Furthermore this check
should be removed and handled by netlink 802.15.4 interface.
