Subject: [PATCH] sound: soc: ti: omap3pandora: fix stale ARM machine ID check to use DT

From: Ethan Nelson-Moore <[email-masked]>
Date: Fri, 8 May 2026 19:08:08 -0700

The omap3pandora driver contains a check for the ARM machine ID via the
machine_is_omap3_pandora() macro. This check is incorrect because the
machine concerned now supports only FDT booting, which does not use
machine IDs, and therefore it will always fail. The legacy board file
for this machine was removed in commit 7fcf7e061edd ("ARM: OMAP2+:
Remove legacy booting support for Pandora"). To resolve this issue, use
of_machine_is_compatible() instead.

Fixes: b715da74deaf ("ARM: dts: omap3-pandora: add OMAP3530 600 MHz version")
Fixes: 9ccd0106c9db ("ARM: dts: omap3-pandora: add DM3730 1 GHz version")
