From: Aaro Koskinen Date: Sun, 22 Mar 2015 15:37:47 +0000 (+0200) Subject: staging: octeon-usb: remove useless prefix from internal routines X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=68d435dd54ecfe7cb34d57204ed3ea4691fb83ea;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git staging: octeon-usb: remove useless prefix from internal routines Original CVMX code used "__" to distinguis internal USB functions from public ones. But in Linux all cvmx_usb routines are internal to this driver, so such separation is useless.
