From c7bd25e8e23c934d8ad420ea93a508edf1588905 Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Wed, 21 Mar 2018 06:29:02 -0400 Subject: [PATCH] staging: iio: tsl2x7x: remove unnecessary code As a follow up to the work in commit a0722d05a195 ("staging: iio: tsl2x7x: convert mutex_trylock() to mutex_lock()"), this patch removes the unnecessary calls to tsl2x7x_get_prox() and tsl2x7x_get_lux() in tsl2x7x_event_handler(). Previously, these functions were locked with mutex_trylock(), but that is no longer the case. This patch also removes a comment that is no longer relevant about returning the last sample.
