Subject: [PATCH v2 5/5] tty: serial: amba-pl011: unindent pl011_console_get_options function body
Date: Thu, 16 Nov 2023 11:31:08 +0100 [thread overview]
Message-ID: <20231116-mbly-uart-v2-5-863f665ce520@bootlin.com> (raw)
In-Reply-To: <20231116-mbly-uart-v2-0-863f665ce520@bootlin.com>
The whole function body is encapsulated inside an if-condition. Reverse
the if logic and early return to remove one indentation level.
Also turn two nested ifs into a single one at the end of the function.
