regmap: debugfs: Don't bother actually printing when calculating max length

2015-09-19T14:38:12Z

The in kernel snprintf() will conveniently return the actual length of the printed string even if not given an output beffer at all so just do that rather than relying on the user to pass in a suitable buffer, ensuring that we don't need to worry if the buffer was truncated due to the size of the buffer passed in.

regmap: debugfs: Ensure we don't underflow when printing access masks

2015-09-19T14:38:11Z

If a read is attempted which is smaller than the line length then we may underflow the subtraction we're doing with the unsigned size_t type so move some of the calculation to be additions on the right hand side instead in order to avoid this.

regmap: fix a NULL pointer dereference in __regmap_init

2015-08-31T10:38:36Z

__regmap_init() may receive a NULL `struct regmap_bus *bus' pointer, for example, from snd_hdac_regmap_init(), and it make sure that it does not NULL deference `bus`, except around ->max_raw_read and ->max_raw_write initialisation. Add missing check. Signed-off-by: Sergey Senozhatsky Signed-off-by: Mark Brown

regmap: Support bulk reads for devices without raw formatting

2015-08-31T10:15:07Z

When doing a bulk read from a device which lacks raw I/O support we fall back to doing register at a time reads but we still use the raw formatters in order to render the data into the word size used by the device (since bulk reads still operate on the device word size rather than unsigned ints). This means that devices without raw formatting such as those that provide reg_read() are not supported. Provide handling for them by copying the values read into native endian values of the appropriate size. Signed-off-by: Mark Brown
