- Subject: [PATCH] common.c: fix kernel 5.10 builds with CONFIG_PM enabled
-
- Building the xr_usb_serial module fails for Kenel 5.10 with CONFIG_PM
- enabled:
-
- xr_usb_serial_common.c:1574:15: error: 'ASYNCB_INITIALIZED' undeclared
- (first use in this function); did you mean 'RCU_INITIALIZER'?
-
- Use tty_port_initialized in order to determine the status of the TTY
- port. This is compatible with Kernel 5.10 and at least Kernel 5.4.
