X-Git-Tag: howlett/maple/20220722_2~2069^2~28^2 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=553715feaa9e0453bc59f6ba20e1c69346888bd5;p=users%2Fjedix%2Flinux-maple.git can: peak_usb: pcan_usb_fd_decode_status(): remove unnecessary test on the nullity of a pointer Since alloc_can_err_skb() puts NULL in cf in the case when skb cannot be allocated and can_change_state() handles the case when cf is NULL, the test on the nullity of skb is now unnecessary.
