Marian Buschsieweke	16f859dafd	drivers/saul: use const qualifier for data to write ... This makes life easier when calling e.g. `saul_reg_write()` with data stored in flash. As now the signatures for reading and writing differ (in that `const` qualifier only), `saul_notsup()` is split into `saul_write_notsup()` and `saul_read_notsup()`. However, one is implemented as a symbol alias of the other, so that ROM consumption remains unchanged.	2022-05-23 08:35:27 +02:00
Kees Bakker	9ed7d2dc18	drivers/ds18: refactor functions with const dev pointer ... All DS18 functions have a dev argument. All except the init function use it as an IN parameter, so we can prototype it as const ds18_t*. As a consequence we can drop the cast in read_temperature() in ds18_saul.c which was the primary trigger for the changes. The commit also follows the preferred convention that "params" is a field in the device struct. Only the init function needs to write it.	2019-01-08 19:25:13 +01:00
