Subject: [PATCH v3 2/4] coresight: pass THIS_MODULE implicitly through a macro
Date: Wed, 22 Apr 2026 18:49:04 +0900 [thread overview]
Message-ID: <20260422-acpi_mod_name-v3-2-a184eff9ff6f@sony.com> (raw)
In-Reply-To: <20260422-acpi_mod_name-v3-0-a184eff9ff6f@sony.com>
Rename coresight_init_driver() to __coresight_init_driver() and replace
it with a macro wrapper that passes THIS_MODULE implicitly. This is in line with
what other buses do.
Suggested-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
