Linus Torvalds 8e1e49550d TTY/Serial driver changes for 6.6-rc1
Here is the big set of tty and serial driver changes for 6.6-rc1.
 
 Lots of cleanups in here this cycle, and some driver updates.  Short
 summary is:
   - Jiri's continued work to make the tty code and apis be a bit more
     sane with regards to modern kernel coding style and types
   - cpm_uart driver updates
   - n_gsm updates and fixes
   - meson driver updates
   - sc16is7xx driver updates
   - 8250 driver updates for different hardware types
   - qcom-geni driver fixes
   - tegra serial driver change
   - stm32 driver updates
   - synclink_gt driver cleanups
   - tty structure size reduction
 
 All of these have been in linux-next this week with no reported issues.
 The last bit of cleanups from Jiri and the tty structure size reduction
 came in last week, a bit late but as they were just style changes and
 size reductions, I figured they should get into this merge cycle so that
 others can work on top of them with no merge conflicts.
