[PATCH v2 08/15] thermal/drivers/tsens: Drop single-cell code for msm8939

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no dtsi file for msm8939 in the kernel sources. Drop the
compatibility with unofficial dtsi and remove support for handling the
single-cell calibration data on msm8939.
