Build error in timer-atmel-pit.c

Build error in timer-atmel-pit.c

[Brent Taylor]

Daniel,
   After updating to linux-4.8-rc4, I got the following build error:

linux-x.yy/drivers/clocksource/timer-atmel-pit.c: In function
'at91sam926x_pit_dt_init':
linux-x.yy/drivers/clocksource/timer-atmel-pit.c:264:2: error: 'ret'
undeclared (first use in this function)
  ret = clk_prepare_enable(data->mck);
  ^~~
linux-x.yy/drivers/clocksource/timer-atmel-pit.c:264:2: note: each
undeclared identifier is reported only once for each function it
appears in

This was introduced in commit: 699e36e5b8e9f77b2be4c23f0b309e53be4b2880

Regards,
Brent Taylor

[PATCH] clocksource/drivers/atmel-pit: Fix compilation error

[Daniel Lezcano]

The previous fix introduced a check against the ret variable which
is not defined, hence producing a compilation error:

linux/drivers/clocksource/timer-atmel-pit.c: In function ‘at91sam926x_pit_dt_init’:
linux/drivers/clocksource/timer-atmel-pit.c:264:2: error: ‘ret’ undeclared (first use in this function)
  ret = clk_prepare_enable(data->mck);
  ^
linux/drivers/clocksource/timer-atmel-pit.c:264:2: note: each undeclared identifier is reported only once for each function it appears in

Add the missing the variable 'ret'.

The previous fix introduced a check against the ret variable which

Add the missing the variable 'ret'.
