sony-laptop fix for 5.6 and 5.7

[Mattia Dongili]

commit 95e2c5b0fd6d7a022f37e7c762ea093aba7b8e34 upstream

platform/x86: sony-laptop: SNC calls should handle BUFFER types

After commit 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer
objects for ASL create_field() operator") ACPICA creates buffers even
when new fields are small enough to fit into an integer.
Many SNC calls counted on the old behaviour.
Since sony-laptop already handles the INTEGER/BUFFER case in
sony_nc_buffer_call, switch sony_nc_int_call to use its more generic
function instead.

ACPICA broke resume from s2ram for some Vaio laptops in 5.6. The
platform drivers maintainers didn't send the fix for 5.7, so the commit
is needed both on 5.6 and on 5.7.

Thanks

I do not see that commit id in Linus's tree.  Are you sure it is
correct?

Heh, no. I didn't rebase my local tree... rookie mistake.
It should be 47828d22539f76c8c9dcf2a55f18ea3a8039d8ef.

I noticed that Sasha Levin autoselected for 5.7 both the patches for
sony-laptop related to the ACPI breakage.
So they are only missing in 5.6 at this point and it's worth getting
both even though only 47828d22539f should be sufficient.

The two commit ids that were picked up for 5.7 are:

[ Upstream commit 47828d22539f76c8c9dcf2a55f18ea3a8039d8ef ]
[ Upstream commit 476d60b1b4c8a2b14a53ef9b772058f35e604661 ]

Thanks, I'll go queue those up now.
