Yes, please. And specify the target tree in the subject, please. See
patchwork warning [1, 2]. The first patch is a clear bug fix, so it
should be targeted to the 'net' tree, while the second patch despite
its usefulness could not be considered a bug fix, so it should be
targeted to the 'net-next' tree. Subjects could be like this:

[PATCHv3 net 1/2] wwan: core: Avoid returning NULL from wwan_create_dev()
[PATCHv3 net-next 2/2] wwan: core: Unshadow error code returned by
ida_alloc_range()

Or since the second patch is not depends on the first one and patches
target different trees, patches could be submitted independently:

[PATCHv3 net] wwan: core: Avoid returning NULL from wwan_create_dev()
[PATCHv3 net-next] wwan: core: Unshadow error code returned by ida_alloc_range()
