+Subject: drm/vmwgfx: Fix incorrect write to read-only register v2:
+
+From: Thomas Hellstrom <thellstrom@vmware.com>
+
+commit 4e578080ed3262ed2c3985868539bc66218d25c0 upstream.
+
+Commit "drm/vmwgfx: correct fb_fix_screeninfo.line_length", while fixing a
+vmwgfx fbdev bug, also writes the pitch to a supposedly read-only register:
+SVGA_REG_BYTES_PER_LINE, while it should be (and also in fact is) written to
+SVGA_REG_PITCHLOCK.
+
+This patch is Cc'd stable because of the unknown effects writing to this
+register might have, particularly on older device versions.
+
+v2: Updated log message.
