From: Lino Sanfilippo Date: Sun, 7 Apr 2024 00:27:09 +0000 (+0200) Subject: serial: ar933x: Remove unneeded static structure X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fff4a5d5609db86ccdf1cf5791b7651b7f6a9b19;p=linux.git serial: ar933x: Remove unneeded static structure In case that no RTS GPIO is available do not use a dedicated nullified serial_rs485 struct to disable RS485 support, but simply delete the SER_RS485_ENABLED flag in the ports rs485_supported struct. This make the structure superfluous and it can be removed.
