Subject: [PATCH] media: pci: mgb4: include linux/errno.h
Date: Fri,  7 Mar 2025 11:24:27 +0100	[thread overview]
Message-ID: <20250307102431.73506-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

The errno.h header is not always included indirectly, leading
to rare randconfig build warnings.

drivers/media/pci/mgb4/mgb4_regs.c:20:11: error: use of undeclared identifier 'EINVAL'
   20 |                 return -EINVAL;
