Commit b310de784bacd ("net: ipa: add IPA v4.7 support") was merged
despite an unresolved comment made by Konrad Dybcio. Konrad
observed that the IMEM region specified for IPA v4.7 did not match
that used downstream for the SM7225 SoC. In "lagoon.dtsi" present
in a Sony Xperia source tree, a ipa_smmu_ap node was defined with a
"qcom,additional-mapping" property that defined the IPA IMEM area
starting at offset 0x146a8000 (not 0x146a9000 that was committed).
The IPA v4.7 target system used for testing uses the SM7225 SoC, so
we'll adhere what the downstream code specifies is the address of
the IMEM region used for IPA.

Why is it tagged for net-next then? ????️
Let's treat it as a normal fix with a Fixes tag and for net.
I reckon the commit message makes is sufficiently clear that
I'm to blame :)

Sorry about that, I was confused, thinking it is only
needed in 6.2-rc--the current release cycle. But that's
not the way it works. I guess I wasn't fully recovered
from the holiday break.
I'll re-send and base it on net/master. Thanks.
