[PATCH] mm: zswap: remove unnecessary check in zswap_find_zpool()

From: Yosry Ahmed
Date: Mon Mar 11 2024 - 19:52:23 EST


zswap_find_zpool() checks if ZSWAP_NR_ZPOOLS > 1, which is always true.
This is a remnant from a patch version that had ZSWAP_NR_ZPOOLS as a
config option and never made it upstream. Remove the unnecessary check.
