Subject: uqmi: fix big endian bugs in MBIM code
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=eb1dec7d0dc283a7f61aa574a443a0ab61f8793f;p=oweals%2Fuqmi.git

uqmi: fix big endian bugs in MBIM code

All MBIM integer fields are 32bit little endian.  So we need to convert
then all on big endian systems.

Fixes: e69bf24b00d8 ("uqmi: add support for MBIM devices with QMI service")
