[PATCH 00/10 V2] rtlwifi: Various clean-ups for the hwinfo routines

[PATCH 00/10 V2] rtlwifi: Various clean-ups for the hwinfo routines

[Larry Finger]

The rtlwifi family of drivers use similar routines to extract hardware
information from EFUSE. This set of patches create a common routine to
extract this data, and converts most of the drivers to use this routine.

In addition, a complicated set of if ... else if ... else statements are
present in rtl8723ae. These are converted into switch statements that
are much easier to read.

The changes in the hwinfo routines was suggested by Arnd Bergmann.

All of this material is intended for kernel 4.8.

[PATCH v2 01/10] rtlwifi: Create common routine to get hardware info

[Larry Finger]

All of the rtlwifi family of drivers have a similar routine that acquires
the hardware info from efuse and initializes a number of variables in the
driver's private area. A common routine is created for all drivers to use.
