Subject: can: can327: remove casts from tty->disc_data
X-Git-Tag: v6.6.7~2018^2~123
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a35f38991c2e22c41aa9cd67bd6c55de5d9972dc;p=platform%2Fkernel%2Flinux-starfive.git

can: can327: remove casts from tty->disc_data

tty->disc_data is 'void *', so there is no need to cast from that.
Therefore remove the casts and assign the pointer directly.
