[PATCH 16/38] staging/bcm: move IOCTL_BCM_SWITCH_TRANSFER_MODE case out to its own function.

From: Dave Jones
Date: Thu Feb 13 2014 - 14:54:38 EST


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.
