scsi: bfa: integer overflow in debugfs
[ Upstream commit 3e351275655d3c84dc28abf170def9786db5176d ]
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").
Fixes: ab2a9ba189e8 ("[SCSI] bfa: add debugfs support")
