Subject: [PATCH v3 18/36] soc: fsl: qe: don't use NO_IRQ in qe_ic.c
Date: Fri, 1 Nov 2019 13:41:52 +0100 [thread overview]
Message-ID: <20191101124210.14510-19-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <20191101124210.14510-1-linux@rasmusvillemoes.dk>
This driver is currently PPC-only, and on powerpc, NO_IRQ is 0, so
this doesn't change functionality. However, not every architecture
defines NO_IRQ, and some define it as -1, so the detection of a failed
irq_of_parse_and_map() (which returns 0 on failure) would be wrong on
those. So to prepare for allowing this driver to build on other
architectures, drop all references to NO_IRQ.
