Subject: [PATCH] media: radio-cadet, initialize timer with setup_timer

From: Matej Hulín <mito.hulin@...il.com>

Stop accessing timer struct members directly and use the setup_timer
helper intended for that use. It makes the code cleaner and will allow
for easier change of the timer struct internals.
