[PATCH 13/17] tty: srmcons: use 'buf' directly in srmcons_do_write()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no need to have a separate iterator ('cur') through 'buf' in
srmcons_do_write(). 'buf' can be used directly which simplifies the code
a bit.
