Use vzalloc instead of vmalloc followed by memset 0.

scsi: bfa: integer overflow in debugfs

2017-10-17T02:35:13+00:00

We could allocate less memory than intended because we do:

	bfad->regdata = kzalloc(len << 2, GFP_KERNEL);

The shift can overflow leading to a crash.  This is debugfs code so the
impact is very small.  I fixed the network version of this in March with
commit 13e2d5187f6b ("bna: integer overflow bug in debugfs").

lseek(fd, n, SEEK_END) does not go to eof - n

When you copy some code, you are supposed to read it.  If nothing else,
there's a chance to spot and fix an obvious bug instead of sharing it...
