zram: fix Kconfig dependency warning
ZSMALLOC depends on MMU so ZRAM should also depend on MMU since 'select' does not follow any dependency chains. Fixes this Kconfig warning: WARNING: unmet direct dependencies detected for ZSMALLOC Depends on [n]: MMU [=n] Selected by [y]: - ZRAM [=y] && BLK_DEV [=y] && BLOCK [=y] && SYSFS [=y] && (CRYPTO_LZO [=y] || CRYPTO_ZSTD [=m] || CRYPTO_LZ4 [=m] || CRYPTO_LZ4HC [=n] || CRYPTO_842 [=n]) Link: https://lkml.kernel.org/r/20220522204027.22964-1-rdunlap@infradead.org Fixes: b3fbd58fcbb10 ("mm: Kconfig: simplify zswap configuration") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: Minchan Kim <minchan@kernel.org> Cc: Nitin Gupta <ngupta@vflare.org> Cc: Sergey Senozhatsky <senozhatsky@chromium.org> Cc: Jens Axboe <axboe@kernel.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
