Subject: [Buildroot] [PATCH] package/igh-ethercat: backport upstream commit to fix build issue
Date: Sun, 12 Jan 2025 17:41:35 +0100	[thread overview]
Message-ID: <20250112164136.213929-1-thomas.petazzoni@bootlin.com> (raw)

This patch backports an upstream igh-ethercat commit to fix build
issues at -O0 or -Os. The commit message says -O0, but in the context
of Buildroot, the issue was encountered at -Os, due to dead-code
elimination.

Fixes:
