Subject: most: remove usage of the deprecated ida_simple_xx() API
X-Git-Tag: v6.11-rc1~84^2~42
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b737a221702c7b6080a72ab671eac938f4768318;p=thirdparty%2Fkernel%2Flinux.git

most: remove usage of the deprecated ida_simple_xx() API

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.
