From: Alexander Sverdlin Date: Wed, 7 Sep 2022 12:16:29 +0000 (+0200) Subject: of: irq: Report individual failures in of_irq_init() X-Git-Tag: v6.6.17~6413^2~36 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=27244cbda82787c9283ce79f5e7bea8ecaa58dff;p=platform%2Fkernel%2Flinux-rpi.git 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.
