[PATCH 06/17] can: dev: fix type of get_can_dlc() and get_canfd_dlc() macros

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Vincent Mailhol <mailhol.vincent@xxxxxxxxxx>

The macros get_can_dlc() and get_canfd_dlc() are not visible in
userland. As such, type u8 should be preferred over type __u8.
