Merge branch 'qca_spi-improvements' 

Stefan Wahren says:

====================
qca_spi: collection of improvements

This series contains a wild collection of improvements for the
qca_spi driver. This is a follow-up series to the recent bugfixes [1].

Patch 1, 2 & 3 in this series is the initially intended rework of
netdev_open/close. Patch 4 & 10 are minor functional improvements and
the rest is clean-up.

Changes in V4:
- keep thread handling in netdev_open, but improve this by two
  separate patches ( 1 & 2 )
- add missing link to bugfix series

Changes in V3:
- rebase on net-next-20240124
- improve commit message in Patch 8
- add Reviewed-by's from Jacob Keller
- add Patch 13 for mailmap as suggested by Jacob
- add Patch 14 for MAINTAINERS entry

Changes in V2:
- rebase on net-next-20231218
- improve cover letter

[1] - https://lore.kernel.org/netdev/20231206141222.52029-1-wahrenst@gmx.net/
