From 1fcf689181e95f3a289f42806fff38fb15a66b61 Mon Sep 17 00:00:00 2001 From: "Ahmed S. Darwish" Date: Mon, 26 Oct 2020 15:03:13 +0100 Subject: [PATCH] USB: serial: digi_acceleport: remove in_interrupt() usage The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The debug printk() in digi_write() prints in_interrupt() as context information. This information is imprecise as it does not distinguish between hard-IRQ or disabled bottom half and it does not consider disabled interrupts or preemption. It is not really helpful. Remove the in_interrupt() printout. Signed-off-by: Ahmed S.
