Re: [PATCH] staging: media: make use of devm_platform_ioremap_resource

Hello Hariprasad,

Thank you for the patch.

As the patch only touches the omap4iss driver, you could have made the
subject line a bit more specific, for instance "staging: media:
omap4iss: Use devm_platform_ioremap_resource". No big deal though.
