Subject[130/205] USB: musb_core: make disconnect and suspend interrupts work again
2.6.34-stable review patch.  If anyone has any objections, please let us know.

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

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

commit 7d9645fdca444d53907b22a4b73e3967efe09781 upstream.

Commit 1c25fda4a09e8229800979986ef399401053b46e (usb: musb: handle irqs in the
order dictated by programming guide) forgot to get rid of the old 'STAGE0_MASK'
filter for calling musb_stage0_irq(), so now disconnect and suspend interrupts
are effectively ignored...
