serial: doc: Re-add paragraph documenting uart_console_write()
Commit 834392a7d92677ff ("serial: doc: Un-document non-existing uart_write_console()") removed a paragraph about a helper function that seemed to never exist. Peter Hurley pointed out that the function does exist, but is called differently. Re-add the paragraph, with the function name corrected. Fixes: 834392a7d92677ff ("serial: doc: Un-document non-existing uart_write_console()") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

@@ -28,6 +28,11 @@ The serial core provides a few helper functions. This includes identifing
the correct port structure (via uart_get_console) and decoding command line
arguments (uart_parse_options).
+There is also a helper function (uart_console_write) which performs a
+character by character write, translating newlines to CRLF sequences.
+Driver writers are recommended to use this function rather than implementing
+their own version.
