1351 This single function is key to pretty much everything. The pvrusb2
1352 device can logically be viewed as a series of subsystems which can be
1353 stopped / started or unconfigured / configured. To get things streaming,
1354 one must configure everything and start everything, but there may be
1355 various reasons over time to deconfigure something or stop something.
1356 This function handles all of this activity. Everything EVERYWHERE that
1357 must affect a subsystem eventually comes here to do the work.
1358
1359 The current state of all subsystems is represented by a single bit mask,
1360 known as subsys_enabled_mask. The bit positions are defined by the
1361 PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any
1362 time the set of configured or active subsystems can be queried just by
1363 looking at that mask. To change bits in that mask, this function here
1364 must be called. The "msk" argument indicates which bit positions to
1365 change, and the "val" argument defines the new values for the positions
1366 defined by "msk".
1367
1368 There is a priority ordering of starting / stopping things, and for
1369 multiple requested changes, this function implements that ordering.
1370 (Thus we will act on a request to load encoder firmware before we
1371 configure the encoder.) In addition to priority ordering, there is a
1372 recovery strategy implemented here. If a particular step fails and we
1373 detect that failure, this function will clear the affected subsystem bits
1374 and restart. Thus we have a means for recovering from a dead encoder:
1375 Clear all bits that correspond to subsystems that we need to restart /
1376 reconfigure and start over.
