Subject: ieee802154 socket: No need to check for ARPHRD_IEEE802154 in raw_bind().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=66a3297f6d3f9dc35e27c3cec6b4437ac13f07ff;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ieee802154 socket: No need to check for ARPHRD_IEEE802154 in raw_bind().

ieee802154_get_dev() only returns devices that have dev->type ==
ARPHRD_IEEE802154, therefore, there is no need to check this again
in raw_bind().
