Subject: [PATCH] zram: ZRAM_DEF_COMP should depend on ZRAM
When Compressed RAM block device support is disabled, the
CONFIG_ZRAM_DEF_COMP symbol still ends up in the generated config file:
CONFIG_ZRAM_DEF_COMP="unset-value"
While this causes no real harm, avoid polluting the config file by
adding a dependency on ZRAM.
Fixes: 917a59e81c342f47 ("zram: introduce custom comp backends API")
