mmc: dw_mmc: Remove set-but-unused variable.

count is only ever used by assigning to old_len if count == 0, and then old_len isn't ever used at all. So, both are redundant. Fixes: drivers/mmc/host/dw_mmc.c: In function ‘dw_mci_read_data_pio’: drivers/mmc/host/dw_mmc.c:1034:32: warning: variable ‘old_len’ set but not used [-Wunused-but-set-variable] Signed-off-by: Chris Ball <[email protected]> Acked-by: Will Newton <[email protected]>
