ext4: simplify some code in read_mmp_block()
My static check complains because we have:
if (!*bh)
return -ENOMEM;
if (*bh) {
The second check is unnecessary.
I've simplified this code by moving the "if (!*bh)" checks around. Also
Andreas Dilger says we should probably print a warning if sb_getblk()
fails.
[ Restructured the code so that we print a warning message as well if
the mmp block doesn't check out, and to print the error code to
disambiguate between the error cases. - TYT ]
