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 [1]: https://lore.kernel.org/all/20240322132619.6389-1-wsa+renesas@sang-engineering.com/ Signed-off-by: Easwar Hariharan <eahariha@linux.microsoft.com> --- drivers/gpu/drm/gma500/cdv_intel_lvds.c | 2 +- drivers/gpu/drm/gma500/intel_bios.c | 22 ++++++++++----------- drivers/gpu/drm/gma500/intel_bios.h | 4 ++-- drivers/gpu/drm/gma500/intel_gmbus.c | 2 +- drivers/gpu/drm/gma500/psb_drv.h | 2 +- drivers/gpu/drm/gma500/psb_intel_drv.h | 2 +- drivers/gpu/drm/gma500/psb_intel_lvds.c | 4 ++-- drivers/gpu/drm/gma500/psb_intel_sdvo.c | 26 ++++++++++++------------- 8 files changed, 32 insertions(+), 32 deletions(-)
