Devm_ functions allocate memory that is released when a driver detaches. Replace kzalloc with devm_kzalloc and remove corresponding kfrees from probe and remove functions of a platform device. Also, unnecessary labels have been removed. Signed-off-by:

Replace devm_kzalloc with devm_kcalloc to ensure there are no integer overflows from the multiplication of a number * sizeof The following Coccinelle semantic patch was used to make this change: //<smpl> @@ expression dev,E1,E2,E3,E4; @@ - devm_kzalloc(dev,E1*E2*sizeof(E3),E4) + devm_kcalloc(dev,E1*E2,sizeof(E3),E4) //</smpl> Signed-off-by:

Unnecessary spi_set_drvdata() has been removed since the driver core clears the driver data to NULL after device release or on probe failure. There is no need to manually clear the device driver data to NULL. The Coccinelle semantic patch used to make this change is as follows: @@ struct spi_device *spi; @@ - spi_set_drvdata(spi, NULL); // </smpl> Due to this removal, variable `spi` was unused so dropped `spi` Signed-off-by:

Prevent a kernel panic by avoiding the use of the BUG_ON macro. Checkpatch detected this issue. The BUG_ON macro is not needed as such cases shouldn't happen and they were introduced for debugging purposes. Signed-off-by:
