category: bugfix

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5ad7a998ba921e37d7e373a2d70d7da401b27f94

--------------------------------

zsmalloc is not exclusive to zswap.  Commit b3fbd58f ("mm: Kconfig:
simplify zswap configuration") made CONFIG_ZSMALLOC only visible when
CONFIG_ZSWAP is selected, which makes it impossible to menuconfig
zsmalloc-specific features (stats, chain-size, etc.) on systems that use
ZRAM but don't have ZSWAP enabled.

Make zsmalloc depend on both ZRAM and ZSWAP.
