NOTIFY_CLOCK_ACCEPTED notification is always generated as a result of GLOBAL_CLOCK_SELECT operation, however NOTIFY_LOCK_CHG notification doesn't, as long as the selected clock is already configured. In the case, ALSA dice driver waits so long. It's inconvenient for some devices to lock to the sequence of value in syt field of CIP header in rx packets. This commit wait just for NOTIFY_CLOCK_ACCEPTED notification by reverting changes partially done by two commits below: * commitfbeac84dbe("ALSA: dice: old firmware optimization for Dice notification") * commitaec045b80d("ALSA: dice: change notification mask to detect lock status change") I note that the successful lock to the sequence of value in syt field of CIP header in rx packets results in NOTIFY_EXT_STATUS notification, then EXT_STATUS_ARX1_LOCKED bit stands in GLOBAL_EXTENDED_STATUS register. The notification can occur enough after receiving the batch of rx packets. When the sequence doesn't include value in syt field of CIP header in rx packets adequate to the device, the notification occurs again and the bit is off.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
