Subject: [PATCH v1 08/12] media: ivtv: Make I2C terminology more inclusive
I2C v7, SMBus 3.2, and I3C 1.1.1 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
