From: Uwe Kleine-König Date: Mon, 7 Jan 2019 19:49:39 +0000 (+0100) Subject: pwm: Drop per-chip dbg_show callback X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cc2d22477779;p=linux.git pwm: Drop per-chip dbg_show callback This callback was introduced in commit 62099abf67a2 ("pwm: Add debugfs interface") in 2012 and up to now there is not a single user. So drop this unused code.
