struct timeval tv is used to get current time.
32-bit systems using 'struct timeval' will break in the year 2038, so
we have to replace that code with more appropriate types.

r8192_priv structure had 2 big arrays with tx gain register values:
- cck_txbbgain_table
- cck_txbbgain_ch14_table
- txbbgain_table

This arrays were read-only - filled in driver init code and look
like firmware/chip-specific.

This patch removes them from r8192_priv and puts them in (global) variables.

tx_bb_gain is also flattened - register values are stored in array;
Amplification value can be calculated using dm_tx_bb_gain_idx_to_amplify().

9 years agostaging: comedi: wrap COMEDI_SRF_FREE_SPRIV usage
Ian Abbott [Tue, 21 Apr 2015 12:18:10 +0000 (13:18 +0100)]
staging: comedi: wrap COMEDI_SRF_FREE_SPRIV usage

The `COMEDI_SRF_FREE_SPRIV` flag in the `runflags` member of `struct
comedi_subdevice` indicates that the memory pointed to by the `private`
member can be automatically freed by the comedi core on subdevice
clean-up (when the low-level comedi device is being "detached").  the
flag doesn't really belong in `runflags`, but it was somewhere
convenient to keep it without having to add a new member to the
structure.

Rather than access the `COMEDI_SRF_FREE_SPRIV` flag directly, use some
new wrapper functions:

* comedi_can_auto_free_spriv(s) - checks whether the subdevice's
  `s->private` points to memory that can be freed automatically.
* comedi_set_spriv_auto_free(s) - marks the subdevice as having a
  `s->private` that points to memory that can be freed automatically.

Export `comedi_set_spriv_auto_free()` for use by the low-level comedi
driver modules, in particular the "amplc_dio200_common" module.
