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 [1]: https://lore.kernel.org/all/20240322132619.6389-1-wsa+renesas@xxxxxxxxxxxxxxxxxxxx/ Signed-off-by: Easwar Hariharan <eahariha@xxxxxxxxxxxxxxxxxxx> --- drivers/media/pci/ivtv/ivtv-i2c.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/drivers/media/pci/ivtv/ivtv-i2c.c b/drivers/media/pci/ivtv/ivtv-i2c.c index c052c57c6dce..967e6a025020 100644 --- a/drivers/media/pci/ivtv/ivtv-i2c.c +++ b/drivers/media/pci/ivtv/ivtv-i2c.c @@ -33,14 +33,14 @@ 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.
