From: Aditya Srivastava <hidden>

Checkpatch expects entries in MAINTAINERS file in a specific order and
warns if the changes made do not follow the specified order.
E.g., running checkpatch on commit 6f736909f0a4 ("MAINTAINERS: Add
patchwork link for PWM entry") reports this warning:
WARNING: Misordered MAINTAINERS entry - list 'Q:' before 'T:'
T: git git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm.git
+Q: https://patchwork.ozlabs.org/project/linux-pwm/list/
Provide a simple fix by swapping the unordered lines
