The board supported by this driver has 2 digital input. Remove the conditional and always init the subdevice. Also, move the subdevice insn_bits function pointer as well as the n_chan out of the boardinfo and use them to initialize the subdevice directly. Since devpriv->s_EeParameters.i_NbrDiChannel for the digital input subdevice is no longer being used, remove initialization of it also. Copy the apci3501_di_insn_bits() function from hwrdv_apci3501.c into the main driver file. Fix the subdev_flags for the subdevice. The only required flag is SDF_READABLE. The SDF_GROUND and SDF_COMMON flags only have meaning for analog subdevices. Remove the len_chanlist initialization, it only has meaning for subdevices that support commands. Remove the io_bits initialization, it only has meaning for digital i/o subdevices that have configurable outputs. Signed-off-by:

The board supported by this driver has a timer device. Remove the conditional and always init the subdevice. Also, move the subdevice insn_* function pointers out of the boardinfo and use them to initialize the subdevice directly. Since devpriv->s_EeParameters.i_Timer is not longer being used, remove its initialization also. Signed-off-by:

This driver is for a simple analog output board with 4 or 8, 14-bit outputs. The board also has 4 digital i/o channels (2 out/2 in) as well as a watchdog or timer. Using the addi-data "common" code in this driver introduces a lot of bloat. Copy the code in addi_common.c to this driver and remove the #include that caused it to be compiled with the driver. This will allow removing the bloat. Rename the auto_attach and detach functions so they have namespace associated with this driver. Signed-off-by:

Instead of coding calling comedi_driver_(un)register and usb_(de)register directly we can use the comedi_usb_driver_(un)register wrapper. This removes some boilerplate and is less error prone. Signed-off-by:

Fold together the NAND driver for Goldfish from Arve with cleanups by Jun Nakajima and a tidy up to 3.7 and checkpatch. This provides a virtual flash driver for the Goldfish Android Virtual Platform, and which is normally used as the root file system when testing emulated devices. Signed-off-by:

A QEMU pipe is a very fast communication channel between the guest system and the emulator. Usage from the guest is simply something like; // connect to special device fd = open("/dev/qemu_pipe", O_RDWR); // tell which service we want to talk to (must be zero-terminated) write(fd, "pipeName", strlen("pipeName")+1); // do read()/write() through fd now ... // close channel close(fd); Signed-off-by:David 'Digit' Turner <digit@android.com> [Added support for parameter buffers for speed] igned-off-by:

Jun Nakajima authored
This imports the current Google code and cleans it up slightly to use pr_ and to properly request its resources. Goldfish is an emulator used for Android development. It has a virtual bus where the emulator passes platform device information to the guest which then creates the appropriate devices. This part of the emulation is not architecture specific so should not be hiding in architecture trees as it does in the Google Android tree. The constants it uses do depend on the platform and the platform creates the bus device which then talks to the emulator to ascertain the actual devices present. Signed-off-by:

On the client side, we have a virtual hcd driver, there actually no hardware interrupts, so we do not need worry about race conditions caused by irq with spinlock held. Turning off irq is not good for system performance after all. Just replace them with a non interrupt safe version. Signed-off-by:

The function 'usbip_event_add()' may be called in interrupt context on the stub side: 'stub_complete'->'stub_enqueue_ret_unlink'->'usbip_event_add'. In this function it tries to get the lock 'ud->lock', so we should disable irq when we get this lock in process context. Signed-off-by:

et131x_get_regs() calls et131x_mii_read(), passing the address of a u32 which is cast to a (u16 *). This works fine for little endian systems, but not for big endian. Change so that the types are cast, not pointers to the types. Reported-by:

The postconfig for drivers that support async commands currently can BUG_ON if the subdevice was improperly configured by the driver.
