A potential bug in drivers/tty/serial/jsm/jsm.ko

[Pavel Andrianov]

Hi!

There is a potential bug in drivers/tty/serial/jsm/jsm.ko.
In neo_parse_isr, line 764 a field ch->ch_flags is updated under 
spinlock protection. In neo_copy_data_from_uart_to_queue the same values 
are written to the field without any protection, as the function is 
always called without locks.
Should the same lock be used in these cases?
