Subject: [PATCH] staging: exfat: remove exfat_fat_sync()
Message-ID: <20200219161738.GA22282@kaaira-HP-Pavilion-Notebook>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

User-Agent: Mutt/1.9.4 (2018-02-28)

Precedence: bulk

exfat_fat_sync() is not called anywhere, hence remove it from
exfat_cache.c and exfat.h
