[GIT PULL] printk for 5.8

[Petr Mladek]

Linus,

please pull the latest printk changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux tags/printk-for-5.8

===============================

+ Benjamin Herrenschmidt solved problem with non-matched console aliases
  by first checking consoles defined on the command line. It is more
  conservative approach than the previous attempts.

+ Benjamin also made sure that the console accessible via /dev/console
  always has CON_CONSDEV flag.

+ Andy Shevchenko added %ptT modifier for printing struct time64_t.
  It extended the existing %ptR handling for struct rtc_time.

+ Bruno Meneguele fixed /dev/kmsg error value returned by unsupported SEEK_CUR.

+ Tetsuo Handa removed unused pr_cont_once().

+ And few small fixes.

==============================

Some changes were originally scheduled already for 5.7. I did not send them
because of non-working hands. We have switched to printk/linux.git with
shared write access to avoid such delays in the future.
