Subject[PATCH v2 0/9] usb: cdns3: Improvements for cdns3 DRD code
Series introduce some improvements to drd.c, drd.h and core.c files of 
cdns3 driver.

Except for the first (1/9) patch that removes not needed function,
the rest patches make improvements suggested by Dan Carpenter
during reviewing CDNSP driver.
CDNSP is the next Cadence USBSSP driver which will be upstreamed.
The DRD part is similar for both CDNS3 and CDNSP and Greg suggested
to merge the similar part of DRD code. As first step I want to merge
some improvements.

Changes for v2:
- Change patch titles as sugested by Peter Chen.
- Remove typos in patch 5 and patch 7.
- Add reviewed-by Peter Chen tag [Patch 1, patch 8 and Patch 9].

Pawel Laszczak (9):
usb: cdns3: core: removed cdns3_get_current_role_driver function
usb: cdns3: drd: removed not needed variables initialization
usb: cnds3: drd: deleted !=
usb: cdns3: drd: return IRQ_NONE explicitly.
usb: cdns3: drd: changed return type from int to bool
usb: cdns3: Added CDNS3_ID_PERIPHERAL and CDNS3_ID_HOST
usb: cdns3: core: removed 'goto not_otg'
usb: cdns3: core: removed overwriting some error code
usb: cdns3: drd: simplify *switch_gadet and *switch_host
