Subject: [42/66] usb: musb: blackfin: call gpio_free() on error path in musb_platform_init()

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Sergei Shtylyov <sshtylyov@...mvista.com>

commit 00be545e49d83485d49a598d3b7e090088934be8 upstream.

Blackfin's musb_platform_init() needs to call gpio_free() for error cleanup iff
otg_get_transceiver() call returns NULL.
