2015-03-30mfd: core: Fix platform-device name collisionsJohan Hovold1-1/+1
Since commit 6e3f62f0793e ("mfd: core: Fix platform-device id generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when registering mfd-devices. Unfortunately, some mfd-drivers rely on the old behaviour of generating platform-device ids by adding the cell id also to the special value of PLATFORM_DEVID_NONE. The resulting platform ids are not only used to generate device-unique names, but are also used instead of the cell id to identify cells when probing subdevices. These drivers should be updated to use PLATFORM_DEVID_AUTO, which would also allow more than one device to be registered without resorting to hacks (see for example wm831x), but lets fix the regression first by partially reverting the above mentioned commit with respect to PLATFORM_DEVID_NONE.

2015-03-12mfd: rtsx_usb: Prevent DMA from stackRoger Tseng1-6/+24
Functions rtsx_usb_ep0_read_register() and rtsx_usb_get_card_status() both use arbitrary buffer addresses from arguments directly for DMA and the buffers could be located in stack. This was caught by DMA-API debug check. Fixes this by using double-buffers via kzalloc in both functions to guarantee the validity of DMA buffer.

In one shot mode, sequencer automatically disables all enabled steps at the end of each cycle. (both ADC steps and TSC steps) Hence these steps need not be saved in reg_se_cache for clearing these steps at a later stage. Also, when ADC wakes up Sequencer should not be busy executing any of the config steps except for the charge step. Previously charge step was 1 ADC clock cycle and hence it was ignored. TSC steps are always disabled at the end of each conversion cycle, hence there is no need to explicitly disable TSC steps by writing 0 to REG_SE.
