[PATCH v0 08/14] media: ivtv: Make I2C terminology more inclusive

I2C v7, SMBus 3.2, and I3C specifications have replaced "master/slave"
with more appropriate terms. Inspired by and following on to Wolfram's
series to fix drivers/i2c/[1], fix the terminology for users of
I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists
in the specification.

Compile tested, no functionality changes intended

     Some more general comments about what we are doing:
 
     The i2c bus is a 2 wire serial bus, with clock (SCL) and data (SDA)
-    lines.  To communicate on the bus (as a master, we don't act as a slave),
+    lines.  To communicate on the bus (as a host, we don't act as a client),
     we first initiate a start condition (ivtv_start).  We then write the
     address of the device that we want to communicate with, along with a flag
-    that indicates whether this is a read or a write.  The slave then issues
+    that indicates whether this is a read or a write.  The client then issues
     an ACK signal (ivtv_ack), which tells us that it is ready for reading /
     writing.  We then proceed with reading or writing (ivtv_read/ivtv_write),
     and finally issue a stop condition (ivtv_stop) to make the bus available
-    to other masters.
+    to other hosts.
 
     There is an additional form of transaction where a write may be
     immediately followed by a read.  In this case, there is no intervening
