X-Git-Tag: accepted/tizen/unified/20240704.075651^0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F88%2F313888%2F1;p=platform%2Fhal%2Fbackend%2Femulator%2Fsensor-emulator.git

Modify to use hal_backend_sensor_funcs allocated from caller

With HAL ABI versioning, the hal_backend_sensor_funcs, which is a
container of sensor backend functions is allocated from hal-api-sensor.
Thus, it is modified to use hal_backend_sensor_funcs allocated from the
caller(hal-api-sensor).
