[ Upstream commit b8d4380365c515d8e0351f2f46d371738dd19be1 ]
In ipa_smem_init(), a Qualcomm SMEM region is allocated (if needed)
and then its virtual address is fetched using qcom_smem_get(). The
physical address associated with that region is also fetched.
The physical address is adjusted so that it is page-aligned, and an
attempt is made to update the size of the region to compensate for
any non-zero adjustment.
But that adjustment isn't done properly. The physical address is
aligned twice, and as a result the size is never actually adjusted.
Fix this by *not* aligning the "addr" local variable, and instead
making the "phys" local variable be the adjusted "addr" value.
