read_current_timer is used in the get_cycles() function when
|
|
|
ce15971 |
ARM_ARCH_TIMER is set, and that function can be inlined into
|
|
|
ce15971 |
driver modules, so we should export the function to avoid
|
|
|
ce15971 |
errors like
|

ce15971 |
ERROR: "read_current_timer" [drivers/video/udlfb.ko] undefined!
