Subject: [PATCH 02/15] modpost: remove unnecessary check in do_acpi_entry()
Date: Wed, 20 Nov 2024 08:56:40 +0900	[thread overview]
Message-ID: <20241119235705.1576946-2-masahiroy@kernel.org> (raw)
In-Reply-To: <20241119235705.1576946-1-masahiroy@kernel.org>

The 'id' pointer is never NULL since it has the same address as
'symval'.

Also, checking (*id)[0] is simpler than calling strlen().
