From: Eric Biggers <ebiggers@xxxxxxxxxx> Previous commits removed all the original CRC kconfig help text, since it was oriented towards people configuring the kernel, and the options are no longer user-selectable. However, it's still useful for there to be help text for kernel developers. Add this.
