Subject[PATCH -next] tty: serial: atmel: driver depends on COMMON_CLK
Date
Since atmel_serial.c uses interfaces that are provided by
the COMMON_CLK Kconfig symbol, the driver should depend on
COMMON_CLK to prevent build errors.

ld: drivers/tty/serial/atmel_serial.o: in function `atmel_serial_pm':
atmel_serial.c:(.text+0x1553): undefined reference to `__clk_is_enabled'
ld: drivers/tty/serial/atmel_serial.o: in function `atmel_set_termios':
atmel_serial.c:(.text+0x1dfe): undefined reference to `__clk_is_enabled'

Fixes: 5e3ce1f26129 ("tty: serial: atmel: Make the driver aware of the existence of GCLK")
