1141 This single function is key to pretty much everything. The pvrusb2
1142 device can logically be viewed as a series of subsystems which can be
1143 stopped / started or unconfigured / configured. To get things streaming,
1144 one must configure everything and start everything, but there may be
1145 various reasons over time to deconfigure something or stop something.
1146 This function handles all of this activity. Everything EVERYWHERE that
1147 must affect a subsystem eventually comes here to do the work.
1148
1149 The current state of all subsystems is represented by a single bit mask,
1150 known as subsys_enabled_mask. The bit positions are defined by the
1151 PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any
1152 time the set of configured or active subsystems can be queried just by
1153 looking at that mask. To change bits in that mask, this function here
1154 must be called. The "msk" argument indicates which bit positions to
1155 change, and the "val" argument defines the new values for the positions
1156 defined by "msk".
1157
1158 There is a priority ordering of starting / stopping things, and for
1159 multiple requested changes, this function implements that ordering.
1160 (Thus we will act on a request to load encoder firmware before we
1161 configure the encoder.) In addition to priority ordering, there is a
1162 recovery strategy implemented here. If a particular step fails and we
1163 detect that failure, this function will clear the affected subsystem bits
1164 and restart. Thus we have a means for recovering from a dead encoder:
1165 Clear all bits that correspond to subsystems that we need to restart /
1166 reconfigure and start over.
