[PATCH 4/6] spi: Constify spi_get_drvdata()'s spi parameter

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


The "spi" parameter of spi_get_drvdata() can be const.
dev_get_drvdata() has been taking a const pointer since commit
7d1d8999b4bec0ba ("i2c: Constify i2c_get_clientdata's parameter").
