Subject: [PATCH] staging: lustre: o2iblnd: fix misleading indentation

The code is correct, the indentation is misleading. Only the the return rc
is part of the conditional statement if rc != 0.

Fix a smatch warning:
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd.c:2157
kiblnd_hdev_setup_mrs() warn: curly braces intended?

Hi,

This patch gives a warning in checkpatch.pl for the line:
if (hdev->ibh_mrs == NULL)

It would be cleaner if this was 'if (!hdev->ibh_mrs)' instead. I didn't fix
this as well because the file has 41 instances of comparisons with NULL. I
would be happy to do so in a patch in reply to this one if it would be good.

Thanks,
Luis
