libqmi: the upstream-merged (!470, in no release yet) LOC Register Events client-identification TLVs, taken verbatim from upstream main (532de37e). modemmanager: the AFW engine unlock + Position Report derivation (!1463, still draft upstream, review-hardened and verified on device). Both as patches on Alpine's git-snapshot aports, pkgrel=100. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Subject: [PATCH] intel: XMM7360: fix big-endian handling of ASN integer output
|
|
|
|
xmm7360_byte_array_read_asn_int() previously always returned
|
|
*out_val from the union member `value.l`, regardless of the actual
|
|
integer size. On big-endian systems, this caused 1-byte or 2-byte
|
|
values to be shifted incorrectly (e.g., 1-byte value 0x01 became
|
|
0x01000000).
|
|
|
|
Fix this by selecting the union member that matches the ASN int type.
