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
