[MTD] [NOR] Prevent erase command invocation on suspended chip
while running stress tests we have met cfi_cmdset_0001.c driver issue. Working on multipartitional devices with erase suspend on write feature enabled it is possible to get erase operation invoked on chip with suspended erase. get_chip() looses information about earlier suspended erase and new erase operation gets issued. New erase operations report successful completion, but blocks remain dirty causing, for example, JFFS2 error messages like: ... Newly-erased block contained word 0x20031985 at offset 0x00200000 Newly-erased block contained word 0x20031985 at offset 0x00280000 Newly-erased block contained word 0x20031985 at offset 0x00240000 ... The patch below fixes that issue. Signed-off-by: Alexander Belyakov <alexander.belyakov@intel.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
