mfd_get_cell returns a const, so change the ds1wm client to store a const mfd cell. This silences type mismatch warnings. Since we're guaranteed to have the mfd_cell, we can also simplify the code a bit to get rid of a temporary variable and NULL check.

Use mfd_data for passing information from mfd drivers to mfd clients. The mfd_cell's driver_data field is being phased out. Clients that were using driver_data now access .mfd_data via mfd_get_data(). This changes ds1wm only; mfd drivers with other cells are not modified, with the exception of led_cell. The led_cell.driver_data line is dropped from htc-pasic3.c in this patch as well. It's not used in mainline (there's no leds-pasic3 platform driver), so it should be safe to take care of that here.

No need to explicitly set the cell's platform_data/data_size. Modify clients to use mfd_get_cell helper function instead of accessing platform_data directly. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
This code makes two calls to clk_get, then test both return values and
fails if either failed.
The problem is that in the first inner if, where the first call to
clk_get has failed, it don't know if the second call has failed as well.
So it don't know whether clk_get should be called on the result of the
second call. Of course, it would be possible to test that value again.
A simpler solution is just to test the result of calling clk_get
directly after each call.
The semantic match that finds this problem is as follows:

We want to have just CONFIG_ARCH_OMAP2, 3 and 4. The rest are nowadays just subcategories of these. Search and replace the following: ARCH_OMAP2420 SOC_OMAP2420 ARCH_OMAP2430 SOC_OMAP2430 ARCH_OMAP3430 SOC_OMAP3430 No functional changes.

This is a 1-wire/w1 DS2423 slave driver for reading the values from all 4 counters available DS2423 devices by using standard w1_slave file. In ds2423 the counters are tied to ram pages 12-15 in and each of those ram-pages. Each of these counter values (and asoociated ram page values) are represented as a own line in w1_slave file. Driver has been tested on mips and x86. usage example: cat /sys/bus/w1/devices/1d-00000009b964/w1_slave 00 02 00 00 00 00 00 00 00 6d 38 00 ff ff 00 00 fe ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 02 00 00 00 00 00 00 00 e0 1f 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 5a 0e 5f 18 00 00 00 00 0b 28 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=408882778 00 05 00 00 00 00 00 00 00 8d 39 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff crc=YES c=5 Patch includes also the documentation.

The search/pullup/add/remove device attributes were 0666 which would allow arbitrary users to affect the 1 wire bus. Change to 0664 to prevent that. I found this patch in the Android tree, apparently this has never been sent upstream so doing it now.
