+Subject: fbdev: vt8500lcdfb: Fix dma_free_coherent() cpu_addr parameter
+To: Sasha Levin <sashal@kernel.org>, Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+Cc: Thomas Fourier <fourier.thomas@gmail.com>, Helge Deller <deller@gmx.de>, stable@vger.kernel.org
+Message-ID: <ahg8Ocvb3UFV6Vdl@decadent.org.uk>
+Content-Disposition: inline
+
+From: Ben Hutchings <benh@debian.org>
+
+Before commit 63a11adaceb8 "fbdev/vt8500lcdfb: Initialize fb_ops with
+fbdev macros", the virtual address of the screen buffer was stored in
+the fb_info::screen_base field and not fb_info::screen_buffer.  The
+backport of commit 88b3b9924337 ("fbdev: vt8500lcdfb: fix missing
+dma_free_coherent()") did not take that into account.
+
+Change the cpu_addr parameter to dma_free_coherent() accordingly.
+
+Fixes: 9c3873cccb3f ("fbdev: vt8500lcdfb: fix missing dma_free_coherent()")
