Subject: [PATCH v2 12/41] drm/modes: parse_cmdline: Add support for named modes containing dashes
Date: Mon, 29 Aug 2022 15:11:26 +0200 [thread overview]
Message-ID: <20220728-rpi-analog-tv-properties-v2-12-459522d653a7@cerno.tech> (raw)
In-Reply-To: <20220728-rpi-analog-tv-properties-v2-0-459522d653a7@cerno.tech>
From: Geert Uytterhoeven <geert@linux-m68k.org>
It is fairly common for named video modes to contain dashes (e.g.
"tt-mid" on Atari, "dblntsc-ff" on Amiga). Currently such mode names
are not recognized, as the dash is considered to be a separator between
mode name and bpp.
Fix this by skipping any dashes that are not followed immediately by a
digit when looking for the separator.
