Empty line here perhaps?

I just skimmed over this, not really give it much of a time. Couple of
nits:

Prefix perhaps?

Never use "inline" in a c file.

variable with capital letters? Not nice. Define? You have that multiple
times in the patch.

Pointless cast, isn't it?
You don't need () around "signed_48 & SIGN_BIT_47"
>+ : signed_48);
Return is not a function. Drop the outer "()"s.
The whole fuction can look like:
static s64 convert_s48_to_s64(s64 signed_48)
{
return signed_48 & BIT_ULL(47) ? signed_48 | GENMASK_ULL(63, 48) :
signed_48;
}
Nicer?

You zeroed the struct 4 lines above...
