The variable `of_match` was incorrectly declared as a `bool`.
It is assigned the return value of of_match_device(), which is a pointer of
type `const struct of_device_id *`.

Hello Greg,

Thank you for your review and the helpful feedback.

I've corrected Signed-off-by line to use my real name.
I also updated Fixes tag in the commit.

Regarding the original issue:
I'm not exactly sure why the compiler didn't catch this,
but I assume implicit casting from pointer to bool is allowed in this context.

Thank you for your email!

Best regards,
Seungjin Bae

That line :(

Also, no need for a blank line after Fixes:

That info should go below the --- line, and this is a version 2 of this
change, right?  Take a look at the kernel documentation for how to
number your patch revisions.
