From cfd01356f95ac95801d8eb183b505dd2801dc289 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Thu, 13 Feb 2014 14:46:37 -0500 Subject: [PATCH] staging/bcm: move IOCTL_BCM_SET_MAC_TRACING 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.
