Subject: [PATCH v2 0/5] tty/serial drivers use devm_clk_get_enabled() helpers

The devm_clk_get_enabled() helpers:
    - call devm_clk_get()
    - call clk_prepare_enable() and register what is needed in order to
     call clk_disable_unprepare() when needed, as a managed resource.

This simplifies the code and avoids calls to clk_disable_unprepare().

version 2 changes
1.8250_ingenic modification directly uses return data->line
2.8250_tegra Removes redundant label err_clkdisable
3.atmel_serial abandons the use of devm_clk_get_enabled interface for this file
4.mps2-uart abandons the use of devm_clk_get_enabled interface for run-time issues
5.st-asc abandons the use of devm_clk_get_enabled interface for this file
6.stm32-usart modifies the return method and removes unused labels

Lei Liu (5):
  tty: 8250_ingenic: Use devm_clk_get_enabled() helpers
  tty: 8250_tegra: Use devm_clk_get_enabled() helpers
  tty: 8250_uniphier: Use devm_clk_get_enabled() helpers
  tty: owl-uart: Use devm_clk_get_enabled() helpers
  tty: stm32-usart: Use devm_clk_get_enabled() helpers
