Subject: [PATCH 2/5] partitions: Add Kconfig dependency to clear benign
 compiler warning

From: John Anthony Kazos Jr. <jakj@...-k-j.com>

Adds a dependency to ACORN_PARTITION_RISCIX in fs/partitions/Kconfig to 
prevent compilation of the function riscix_partition which is used only 
within ACORN_PARTITION_CUMANA and ACORN_PARTITION_ADFS sections, thereby 
preventing an unused-function compiler warning if ACORN_PARTITION_RISCIX 
is defined and neither of the other two are.

Signed-off-by: John Anthony Kazos Jr. <jakj@...-k-j.com>

---

Nothing depending on RISCIX is defined except inside CUMANA and ADFS, so 
without either of those, nothing using the RISCIX stuff is compiled, hance 
the unused-function warning.
