This isn't how to document a struct; see Documentation/doc-guide/kernel-doc.rst

/**
* struct do_proc_dointvec_minmax_conv_param - Range checking for sysctls
* @min: Pointer to minimum allowable value.
* @max: Pointer to maximum allowable value.
*
* Provides the minimum and maximum values allowed for a parameter. A

Also, it's inappropriate to document the return value from
proc_dointvec_minmax() here; that should be in the kernel-doc for the
function.
