memstick: rtsx_usb_ms: Manage runtime PM when accessing the device

2016-11-24T02:30:48+00:00

[ Upstream commit 9158cb29e7c2f10dd325eb1589f0fe745a271257 ] Accesses to the rtsx usb device, which is the parent of the rtsx memstick device, must not be done unless it's runtime resumed. This is currently not the case and it could trigger various errors. Fix this by properly deal with runtime PM in this regards. This means making sure the device is runtime resumed, when serving requests via the ->request() callback or changing settings via the ->set_param() callbacks.

memstick: rtsx_usb_ms: Runtime resume the device when polling for cards

2016-11-24T02:30:43+00:00

[ Upstream commit 796aa46adf1d90eab36ae06a42e6d3f10b28a75c ] Accesses to the rtsx usb device, which is the parent of the rtsx memstick device, must not be done unless it's runtime resumed. Therefore when the rtsx_usb_ms driver polls for inserted memstick cards, let's add pm_runtime_get|put*() to make sure accesses is done when the rtsx usb device is runtime resumed.

memstick: mspro_block: add missing curly braces

2015-05-17T23:12:28+00:00

[ Upstream commit 13f6b191aaa11c7fd718d35a0c565f3c16bc1d99 ] Using the indenting we can see the curly braces were obviously intended. This is a static checker fix, but my guess is that we don't read enough bytes, because we don't calculate "t_len" correctly.

memstick: r592: fix build warnings for !PM_SLEEP

2014-10-14T00:18:22+00:00

When PM_SLEEP is not enabled, the r592_clear_interrupts() function is never used. If so, don't build it to prevent a compiler warning. Signed-off-by: Thierry Reding Cc: Maxim Levitsky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/memstick/host/rtsx_pci_ms.c: fix ms card data transfer bug

2014-01-24T00:37:04+00:00

This patch is used to add support for ms card. The main difference between ms card and mspro card is long data transfer mode. mspro card can use auto mode DMA for long data transfer, but ms can not use this mode, it should use normal mode DMA. The memstick core added support for ms card, but the original driver will make ms card fail at initialization, because it uses auto mode DMA. This patch makes the ms card work properly.

tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are reinitialzing the completion, not initializing.

drivers/memstick/core/ms_block.c: fix unreachable state in h_msb_read_page()

2013-11-13T03:09:35+00:00

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 transitioning to MSB_RP_RECIVE_STATUS_REG right after MSB_RP_SEND_READ_STATUS_REG.
