There is a move to deprecate bus-specific PM operations and move to using dev_pm_ops instead in order to reduce the amount of boilerplate code in buses and facilitiate updates to the PM core. Do this move for the ads7846 driver. Signed-off-by: Mark Brown <redacted> --- drivers/input/touchscreen/ads7846.c | 16 ++++++++++------ 1 files changed, 10 insertions(+), 6 deletions(-)
