Subject: [PATCH v7 7/7] fbdev: Rename fb_mem*() helpers
Date:   Fri, 12 May 2023 12:24:44 +0200
Message-Id: <20230512102444.5438-8-tzimmermann@suse.de>
In-Reply-To: <20230512102444.5438-1-tzimmermann@suse.de>
References: <20230512102444.5438-1-tzimmermann@suse.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Update the names of the fb_mem*() helpers to be consistent with their
regular counterparts. Hence, fb_memset() now becomes fb_memset_io(),
fb_memcpy_fromfb() now becomes fb_memcpy_fromio() and fb_memcpy_tofb()
becomes fb_memcpy_toio(). No functional changes.

v6:
	* update new file fb_io_fops.c
