You are supposed to run the patch itself through checkpatch:

$ git format-patch HEAD^!
0001-RDMA-cma-Fix-checkpatch-error.patch
$ scripts/checkpatch.pl 0001-RDMA-cma-Fix-checkpatch-error.patch
WARNING: A patch subject line should describe the change not the tool that found it
#4: 
Subject: [PATCH] RDMA/cma: Fix checkpatch error

WARNING: Possible unwrapped commit description (prefer a maximum 75 chars per line)
#12: 
This patch moves the assignment of ret to the previous line. The if statement then checks the value of ret assigned on the previous line. The assigned value of ret is not changed. Testing involved recompiling and loading the kernel. After the changes checkpatch does not report this the error in cma.c.

total: 0 errors, 2 warnings, 9 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

0001-RDMA-cma-Fix-checkpatch-error.patch has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainer, see CHECKPATCH in MAINTAINERS.
