Subject[PATCH 5.15 032/110] ice: Dont use GFP_KERNEL in atomic context
Date
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 3d97f1afd8d831e0c0dc1157418f94b8faa97b54 ]

ice_misc_intr() is an irq handler. It should not sleep.

Use GFP_ATOMIC instead of GFP_KERNEL when allocating some memory.

Fixes: 348048e724a0 ("ice: Implement iidc operations")
