M Chetan Kumar says:

====================
net: wwan: iosm: fixes

This patch series contains IOSM Driver fixes. Below is the patch
series breakdown.

PATCH1:
* Correct the td buffer type casting & format specifier to fix lkp buildbot
warning.

PATCH2:
* Endianness type correction for nr_of_bytes. This field is exchanged
as part of host-device protocol communication.

PATCH3:
* Correct ul/dl data protocol mask bit to know which protocol capability
does device implement.

PATCH4:
* Calling unregister_netdevice() inside wwan del link is trying to
acquire the held lock in ndo_stop_cb(). Instead, queue net dev to
be unregistered later.
====================
