nvdimm: Remove usage of the deprecated ida_simple_xx() API

2024-01-03T20:21:36Z

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). This is less verbose.

nvdimm: Use kstrtobool() instead of strtobool()

2023-07-19T15:42:50Z

strtobool() is the same as kstrtobool(). However, the latter is more used within the kernel. In order to remove strtobool() and slightly simplify kstrtox.h, switch to the other function name. While at it, include the corresponding header file () Reviewed-by: Vishal Verma Signed-off-by: Christophe JAILLET Signed-off-by: Dave Jiang
