* mtd: maps: lantiq-flash: Convert to platform remove callback returning voidUwe Kleine-König2023-10-161-4/+2
| | | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* mtd: lantiq-flash: drop check of boot selectHauke Mehrtens2017-09-041-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | Do not check which flash type the SoC was booted from before using this driver. Assume that the device tree is correct and use this driver when it was added to device tree. This also removes a build dependency to the SoC code.

* mtd: drop unnecessary partition parser dataBrian Norris2015-11-111-3/+2
| | | | | | | | | | | | | We should assign the MTD dev.of_node instead of the parser data field. This gets us the equivalent partition parser behavior with fewer special fields and parameter passing. Also convert several of these to mtd_device_register(), since we don't need the 2nd and 3rd parameters anymore.
