From 27244cbda82787c9283ce79f5e7bea8ecaa58dff Mon Sep 17 00:00:00 2001 From: Alexander Sverdlin Date: Wed, 7 Sep 2022 14:16:29 +0200 Subject: [PATCH] of: irq: Report individual failures in of_irq_init() New pr_err(), a copy of preceeding pr_debug(), faciliates debugging. This change was inspired by a long lasting debugging of the octeon_irq_init_ciu() which fails completely silently and leaves the interrupt controller half-way configured which in turn had very non-obvious effects.
