This change will allow to use different NVM file based
on WCN3991 BT SoC ID.Need to use different NVM file based on
fab location for WCN3991 BT SoC.

Please indent this properly.

I am also confused about the 0x0000ffff since it is just 16-bit value in the first place. Also where do you want to shift the 32-bit value to.

Frankly, I find all this version magic kinda questionable.

Hi Venkata,

I agree with Marcel that the version magic is confusing ...

Can we at least do the leN_to_cpu conversions in qca_read_soc_version()
as previously to make this less clunky?

And/or define a macro to extract 'soc_ver' to unclunkify this further.

The QCA_ prefix seems a bit verbose, given that this is a QCA driver and
WCN3991 uniquely identifies the chip. Having the prefix just needlessly
clutters conditions, I suggest to just call it SOC_ID_WCN3991.
