2018-01-08pinctrl: at91-pio4: account for const type of of_device_id.dataJulia Lawall1-2/+2
This driver creates a const structure that it stores in the data field of an of_device_id array. Adding const to the declaration of the location that receives the const value from the data field ensures that the compiler will continue to check that the value is not modified. Furthermore, the const-discarding cast on the extraction from the data field is no longer needed. Done using Coccinelle.
