[PATCH printk v2 0/2] nbcon irq_work fixes

[John Ogness]

Hi,

This is v2 of a series to address some irq_work issues with nbcon.
Initially motivated as a workaround for hardware-related regressions
reported [0], it turns out that the workaround is actually a nice
improvement for nbcon deferred printing in general.

v1 is here [1].

John Ogness

The changes since v1:

- Add a preceding patch to flush the irq_work on nbcon_free(). This
  pre-existing issue was reported [2] by Sashiko while it was
  reviewing v1.
