Subject: rust: configfs: use `CStr::as_char_ptr`
X-Git-Tag: v6.19-rc1~175^2~22
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3b46f65355c9627efd2dd8180c96b006a44d30f8;p=thirdparty%2Fkernel%2Flinux.git

rust: configfs: use `CStr::as_char_ptr`

Replace the use of `as_ptr` which works through `<CStr as
Deref<Target=&[u8]>::deref()` in preparation for replacing
`kernel::str::CStr` with `core::ffi::CStr` as the latter does not
implement `Deref<Target=&[u8]>`.
