[PATCH] memstick: fix unreachable state in h_msb_read_page() in ms_block.c

From: rogerable
Date: Wed Oct 30 2013 - 03:57:44 EST


From: Roger Tseng <rogerable@xxxxxxxxxxx>

In h_msb_read_page() in ms_block.c, flow never reaches case
MSB_RP_RECIVE_STATUS_REG. This causes error when MEMSTICK_INT_ERR is
encountered and status error bits are going to be examined, but the status will
never be copied back.

Fix it by transiting to MSB_RP_RECIVE_STATUS_REG right after
MSB_RP_SEND_READ_STATUS_REG.
