| Subject: zram: fix Kconfig dependency warning |
| Date: Sun, 22 May 2022 13:40:27 -0700 |
| |
| 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]) |
