2015-05-14staging: slicoss: fix occasionally writing out only half of a dma addressDavid Matlack2-5/+1
curaddrupper caches the last written upper 32-bits of a dma address (the device has one register for the upper 32-bits of all dma address registers). The problem is, not every dma address write checks and sets curaddrupper. This causes the driver to occasionally not write the upper 32-bits of a dma address to the device when it really should. I've seen this manifest particularly when the driver is trying to read config data from the device (RCONFIG) in order to checksum the device's eeprom. Since the device writes its config data to the wrong DMA address the driver reads 0 as the eeprom size and the eeprom checksum fails. This patch fixes the issue by removing curaddrupper and always writing the upper 32-bits of dma addresses.

2015-05-10android, lmk: avoid setting TIF_MEMDIE if process has already exitedDavid Rientjes1-5/+12
TIF_MEMDIE should not be set on a process if it does not have a valid ->mm, and this is protected by task_lock(). If TIF_MEMDIE gets set after the mm has detached, and the process fails to exit, then the oom killer will defer forever waiting for it to exit. Make sure that the mm is still valid before setting TIF_MEMDIE by way of mark_tsk_oom_victim().

2015-05-10staging: dgap: use remove functionSudip Mukherjee1-25/+24
the remove callback will be called in two cases, 1) if the driver is removed and 2) if the pci device is removed. as of now all the board cleanups were being done in the module unload section so if the module is unloaded everything works. But if the pci device is removed then the loaded driver will be left in an inconsistent state. So moved the cleanups in the remove callback and since there was no reference of dgap_driver in remove_one(), so had to define the pci_driver in the function.

2015-05-10staging: comedi: gsc_hpdi: remove multiple board type supportIan Abbott1-34/+1
The code for determining which board type matches the PCI device ID is over-the-top since only a single board type is supported. Also, the method it uses match the PCI device ID to a board type is a little antiquated. Most comedi drivers for PCI devices use `driver_data` from the probed PCI device as an index into an array of supported board types, but "gsc_hpdi" uses a `for` loop to find an element of `hpdi_boards[]` that matches the PCI device. The only thing in `hpdi_boards[]` not used for finding a matching PCI device is the `name` member of `struct hpdi_board` which points to a string literal and ends up getting assigned to `dev->board_name`. Get rid of the multiple board type support, and set `dev->board_name` to point to the original string literal pointed to by `hpdi_boards[0].name`. This string is visible to userspace.
