[PATCH 1/8] rtlwifi: rtl8723be: Fix module parameter initialization

[Larry Finger]

This driver has a number of errors in the module initialization. These
include the following:

Parameter msi_support is stored in two places - one is removed.
Paramters sw_crypto and disable_watchdog were never stored in the final
locations, nor were they initialized properly.

[PATCH 2/8] rtlwifi: rtl8723ae: Fix initialization of module parameters

[Larry Finger]

This driver has some errors in the handling of module parameters. These
include missing initialization for parameters msi_support and
disable_watchdog. In addition, neither of these parameters nor sw_crypto
are transferred into the locations used by the driver. A final fix is
adding parameter msi to the module named and description macros.

[PATCH 3/8] rtlwifi: rtl8821ae: Fix errors in parameter initialization

[Larry Finger]

This driver failed to copy parameters sw_crypto and disable_watchdog into
the locations actually used by the driver. In addition, msi_support was
initialized three times and one of them used the wrong variable. The
initialization of parameter int_clear was moved so that it is near that
of the rest of the parameters.

Ok, I give up and just ask: are the above hw mapped registers that
actually need to be read/written?  Or am I missing something here, as
the 2 statements above don't seem to make sense.  The same for other
patches in this series.

Cheers,
