From fe59cefb6971ded0f130bbdd3dfeb1fcc9446c31 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Thu, 13 Feb 2014 14:48:09 -0500 Subject: [PATCH] staging/bcm: move IOCTL_BCM_GET_DEVICE_DRIVER_INFO 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.
