      printk: Wake klogd when passing console_lock owner · c14376de
      Petr Mladek authored
      wake_klogd is a local variable in console_unlock(). The information
      is lost when the console_lock owner using the busy wait added by
      the commit dbdda842 ("printk: Add console owner and waiter
      logic to load balance console writes"). The following race is
      possible:
      
      CPU0				CPU1
      console_unlock()
      
        for (;;)
           /* calling console for last message */
      
      				printk()
      				  log_store()
      				    log_next_seq++;
      
           /* see new message */
           if (seen_seq != log_next_seq) {
      	wake_klogd = true;
      	seen_seq = log_next_seq;
           }
      
           console_lock_spinning_enable();
      
      				  if (console_trylock_spinning())
      				     /* spinning */
      
           if (console_lock_spinning_disable_and_check()) {
      	printk_safe_exit_irqrestore(flags);
      	return;
      
      				  console_unlock()
      				    if (seen_seq != log_next_seq) {
      				    /* already seen */
      				    /* nothing to do */
      
      Result: Nobody would wakeup klogd.
      
      One solution would be to make a global variable from wake_klogd.
      But then we would need to manipulate it under a lock or so.
      
      This patch wakes klogd also when console_lock is passed to the
      spinning waiter. It looks like the right way to go. Also userspace
      should have a chance to see and store any "flood" of messages.
      
      Note that the very late klogd wake up was a historic solution.
      It made sense on single CPU systems or when sys_syslog() operations
      were synchronized using the big kernel lock like in v2.1.113.
      But it is questionable these days.

      gpio: Handle deferred probing in of_find_gpio() properly · ce27fb2c
      Chen-Yu Tsai authored
      of_get_named_gpiod_flags() used directly in of_find_gpio() or indirectly
      through of_find_spi_gpio() or of_find_regulator_gpio() can return
      -EPROBE_DEFER. This gets overwritten by the subsequent of_find_*_gpio()
      calls.
      
      This patch fixes this by trying of_find_spi_gpio() or
      of_find_regulator_gpio() only if deferred probing was not requested by
      the previous of_get_named_gpiod_flags() call.

      gpiolib: Keep returning EPROBE_DEFER when we should · 6662ae6a
      Maxime Ripard authored
      Commits c8582339 ("gpio: of: Support SPI nonstandard GPIO properties")
      and 6a537d48 ("gpio: of: Support regulator nonstandard GPIO
      properties") have introduced a regression in the way error codes from
      of_get_named_gpiod_flags are handled.
      
      Previously, those errors codes were returned immediately, but the two
      commits mentioned above are now overwriting the error pointer, meaning that
      whatever value has been returned will be dropped in favor of whatever the
      two new functions will return.
      
      This might not be a big deal except for EPROBE_DEFER, on which GPIOlib
      customers will depend on, and that will now be returned as an hard error
      which means that they will not probe anymore, instead of gently deferring
      their probe.
      
      Since EPROBE_DEFER basically means that we have found a valid property but
      there was no GPIO controller registered to handle it, fix this issues by
      returning it as soon as we encounter it.
