From 0ef78c8d7ac65c6f5c60dd8c8ce1c7075841e8dd Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 10 Jun 2016 16:22:16 +0300 Subject: [PATCH] mmc: block: Fix tag condition with packed writes commit d806b46e5f496a6335ebd7f8432d2533507ce9a2 upstream. Apparently a cut-and-paste error, 'do_data_tag' is using 'brq' for data size even though 'brq' has not been set up. Instead use blk_rq_sectors().
