From 3eccdbcdb75dcbec142d6332075c446473e9b4d6 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Thu, 13 Feb 2014 14:45:31 -0500 Subject: [PATCH] staging/bcm: move BCM_LED_THREAD_STATE_CHANGE_REQ case out to its own function. bcm_char_ioctl is one of the longest non-generated functions in the kernel, at 1906 lines. Splitting it up into multiple functions should simplify this a lot.
