[PATCH 2/4] drivers/scsi/lpfc/lpfc_sli.c: convert GFP_KERNEL to GFP_ATOMIC

Julia Lawall

From: Julia Lawall <julia.lawall@lip6.fr>

The function is called with locks held and thus should not use GFP_KERNEL.

The semantic patch that makes this report is available
in scripts/coccinelle/locks/call_kern.cocci.
