Re: [PATCH 1/5] gpio/omap: Remove bank->id information and misc cleanup

From: DebBarma, Tarun Kanti <hidden>
Date: 2012-02-16 05:53:47
Also in: linux-arm-kernel, linux-devicetree

The driver does not need anymore any id to identify the GPIO instance.
Remove every occurence of the bank->id inside the driver.

Remove two trailing spaces.
Add a dev variable for better readability in probe.
Remove unused variable bank->pbase.

Looks fine.
If needed you can add my Acked-by:
