Typecasting the interrupt number from "unsigned int" to "signed int" to compare with 0(signed int by default).
Declaring interrupt number as "signed int" would violate kernel standards. So typecasting is the possible approach.
The fix is for spi-mpc512x.
This fixes warning such as:
drivers/spi/spi-mpc512x-psc.c:493:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0

Your subject lines are still incorrect :(

Why would it violate kernel standards?
Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
Please fix your mail client to word wrap within paragraphs at something
substantially less than 80 columns. Doing this makes your messages much
easier to read and reply to.
