This enables a much more efficient way of device searching. It uses the
1-wire read-rom operation which allows the direct reading of the slave

This patch introduces the module_usb_driver macro which is a convenience
macro for USB driver modules similar to module_platform_driver. It is
intended to be used by drivers which init/exit section does nothing but
register/unregister the USB driver. By using this macro it is possible
to eliminate a few lines of boilerplate code per USB driver.Based on work done by Lars-Peter Clausen for other
busses (i2c and spi).Cc: Lars-Peter Clausen

This patch generalizes the module_platform_driver macro and introduces a new
module_driver macro. The module_driver macro takes a driver name, a register
and a unregister function for this driver type. Using these it construct the
module init and exit sections which register and unregister the driver. Since
such init/exit sections are commonly found in drivers this macro can be used
to eliminate a lot of boilerplate code.The macro is not intended to be used by driver modules directly, instead it
should be used to generate bus specific macros for registering drivers like
the module_platform_driver macro.Signed-off-by: Lars-Peter Clausen

w1_therm devices can either be bus powered or externally powered.
When device is bus powered during temperature conversion the bus
have to be left high to provide necessary power. Some masters also allow
strong power-up to be enabled in this case.
Naturally, no communication over bus can occur during that time.However, if device has external power then there is no such restriction,
and host can talk to other devices during temperature conversion.There is command which allows us to check how device is powered,
this patch uses it to release the bus on externally w1_therm powered devices
during temperature conversion.Also, this changes uninterruptible sleeps there into interruptible ones to
avoid long uninterruptible sleep if w1 subsystem happens to grab bus for
scan during w1_therm_read().Signed-off-by: Maciej Szmigiero

Almost every platform_driver does the three steps get_resource,
request_mem_region, ioremap. This does not only lead to a lot of code
duplication, but also a huge number of similar error strings and
inconsistent error codes on failure. So, introduce a helper function
which simplifies remapping a resource and make it hard to do something
wrong and add documentation for it.Signed-off-by: Wolfram Sang
