Subject: usb: musb: Fix a bug by making suspend interrupt available in device mode
To: linux-usb@vger.kernel.org
Cc: Maulik Mankad <x0082077@ti.com>, David Brownell <david-b@pacbell.net>, Felipe Balbi <felipe.balbi@nokia.com>
Message-ID: <1276593027-30168-1-git-send-email-x0082077@ti.com>
As a part of aligning the ISR code for MUSB with the specs, the
ISR code was re-written.
See Commit 1c25fda4a09e8229800979986ef399401053b46e (usb: musb: handle
irqs in the order dictated by programming guide)
With this the suspend interrupt came accidently under CONFIG_USB_MUSB_HDRC_HCD.
The fix brings suspend interrupt handling outside
CONFIG_USB_MUSB_HDRC_HCD.
