ezusb_read_ltv() is always invoked via the ->read_ltv() callback. This callback is mostly invoked under orinoco_lock() which disables BH. There are a few invocations during probe which occur in preemptible context via: ezusb_probe() -> orinoco_init() -> determine_fw_capabilities() Extend `hermes_ops' with the ->read_ltv_pr callback which is implemented with the same callback like ->read_ltv on `hermes_ops_local'. On `ezusb_ops' ->read_ltv is used for callbacks under the lock which need to poll. The new ->read_ltv_pr() is used in the preemptible context in which it is possible to wait for the completion. Provide HERMES_READ_RECORD_PR() and hermes_read_wordrec_pr() which behave like their non _pr equivalents and invoke ->read_ltv_pr(). This removes the last user of ezusb_req_ctx_wait() and can now be removed.

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.
