Hi Vijay,

I just have a couple of minors comments.

You should copy at least the file authors when submitting a patch. Paul is missing.

You should correct the subject with something like:
[PATCH] OMAP: omap_device: Fix to support multiple hwmods for a single device

On 8/24/2010 1:03 PM, ABRAHAM, KISHON VIJAY wrote:
Currently there is a bug in the existing omap_device core code when
extracting the hwmod structures passed to omap_device_build_ss(). This bug
gets exposed only when passing multiple HWMOD structure to
omap_device_build_ss() resulting in incorrect extraction from second HWMOD
structure.

This fix uses the pointer to  pointer to OMAP_HWMOD structure (array of
Remove the space here --------^

pointers to OMAP_HWMOD structure) passed to omap_device_build_ss() to
correctly extract the appropriate OMAP_HWMOD structure.

All OMAP_HWMOD structure should be in lower case.


This patch has been created and tested on lo/master and mainline.

Signed-off-by: Kishon Vijay Abraham I<kishon@xxxxxx>

Add Paul & Kevin in CC here after your signed-off. You can add myself as well, since I reviewed your first RFC.

Otherwise the patch looks fine to me.

Thanks,
Benoit
