Hello,
This patch series moves the different driver resources (clks and iomem)
retrieval to the device managed versions (devm_ functions).
Best Regards,
Boris
Changes since v2:
- split urgent fix and resource retrieval improvements
Boris BREZILLON (3):
usb: ohci-at91: replace request_mem_region + ioremap by
devm_request_and_ioremap
usb: ohci-at91: use dev variable instead of &pdev->dev
usb: ohci-at91: use device managed clk retrieval

devm_request_and_ioremap call which does the same things but with device
managed resources.

This function is already deprecated, use devm_ioremap_resource() instead
(it returns error pointer, not NULL on error).

There's no need -- those functions print error messages themselves.

Make use of the dev variable instead of referencing the dev field of the
pdev struct.
