The devm_clk_get_enabled() helper:
- calls devm_clk_get()
- calls clk_prepare_enable() and registers what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code, the error handling paths and avoid the need of
a dedicated function used with devm_add_action_or_reset().
That said, meson_uart_probe_clock() is now more or less the same as
devm_clk_get_enabled(), so use this function directly instead.
This also fixes an (unlikely) unchecked devm_add_action_or_reset() error.
Based on my test with allyesconfig, this reduces the .o size from:
text data bss dec hex filename
16350 5016 128 21494 53f6 drivers/tty/serial/meson_uart.o
down to:
15415 4784 128 20327 4f67 drivers/tty/serial/meson_uart.o

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
