From 726c8277bc5e67799f2ac3ca7fc795d4bf07264f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 19 Oct 2020 12:06:42 +0200 Subject: usb: atm: Replace in_interrupt() usage in comment in_interrupt() is a pretty vague context description as it means: hard interrupt, soft interrupt or bottom half disabled regions. Replace the vague comment with a proper reasoning why spin_lock_irqsave() needs to be used. Signed-off-by: Ahmed S.
