[PATCH linux dev-4.10 v4 00/31] drivers: fsi: client fixes and refactor

[Eddie James]

From: "Edward A. James" <eajames at us.ibm.com>

This series refactors the FSI client device drivers. It adds a number of fixes
discovered from bugs over the past several months. Most critically, it fixes
various race conditions in the unbind/remove pathway of the occ-hwmon, occ,
and sbefifo drivers.

Apologies for spamming the list with so many patches...

Changes since v3:
 * switch checks for OCC client NULL to the common read/write/close functions.
 * add helper function for ugly wait_event_interruptible in OCC read().
 * removed useless check for cancel in occ open().

Changes since v2:
 * split "General clean-up" patches into many more patches
 * Change to wake_up_all() in various places
 * Set sbe pointer NULL and add check in occ-hwmon. For race safety.

Changes since v1:
 * split into multiple patches.
 * add memory management patch.
