Subject: [PATCH 0/5] tty/serial: at91: fix bugs when using multiple serials

The series of patches fix bugs when using multiple serial ports at the same time:
 - The using rx ring buffer in DMA is inconsistent with its allocation.
 - The serial port can't send and receive data when it's opened the second time
   and the later if it switches to PIO when DMA channel is not available.
 - The serial port can lead to kernel crash when data is sending and receiving
   and the program is killed.
 
The patches were made from branch tty-next of gregkh/tty.git repository, and 
tested on a SAMA5D36 VB boards with 5 serial ports enabled.

Leilei Zhao (5):
  tty/serial: at91: correct check of buf used in DMA
  tty/serial: at91: correct buffer size used in DMA
  tty/serial: at91: revise the return type of atmel_init_property
  tty/serial: at91: set ops in property init each time
  tty/serial: at91: correct the usage of tasklet
