Subject: [PATCH 5/5] staging: rtl8723bs: Remove File operation APIs
Date: Wed, 9 Oct 2019 14:32:23 +0200 [thread overview]
Message-ID: <20191009123223.163241-5-hdegoede@redhat.com> (raw)
In-Reply-To: <20191009123223.163241-1-hdegoede@redhat.com>
rtl8723bs had 2 private file operation helpers:
rtw_is_file_readable()
rtw_retrive_from_file()
These were only used by the removed phy_Config*WithParaFile() functions,
so they can be removed now.
Signed-off-by: Hans de Goede <hdegoede@redhat.com>
