* tight-loops). Should be less than ~20ms since usleep_range
|
|
* is used (see Documentation/timers/timers-howto.rst).
|
|
* @timeout_us: Timeout in us, 0 means never timeout
|
|
*
|
|
* Returns 0 on success and -ETIMEDOUT upon a timeout. In either
|
|
* case, the last read value at @addr is stored in @val. Must not
|
|
* be called from atomic context if sleep_us or timeout_us are used.

*
|
|
* This is modelled after the readx_poll_timeout macros in linux/iopoll.h.
