[PATCH] staging: ks7010: Replace macros with do while loop.

From: chakravarthikulkarni
Date: Sun Feb 21 2021 - 15:14:43 EST


This commit fix errors found in checkpath.pl.
Error message is:
<Macros with complex values should be enclosed in parentheses.>
It is a good idea to keep complex macros in do while loop.
Otherwise result may have side effect.
