Subject: [PATCH] selftests/x86/syscall: use ARRAY_SIZE for msbs
Date: Wed,  9 Jun 2021 17:55:06 +0800	[thread overview]
Message-ID: <1623232506-91641-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)

Use ARRAY_SIZE instead of dividing sizeof array with sizeof an
element.

Clean up the following coccicheck warning:

./tools/testing/selftests/x86/syscall_numbering.c:316:35-36: WARNING:
Use ARRAY_SIZE.
