Subject: [PATCH] exfat: fix possible memory leak in exfat_find() 
Git-commit: 94182167ec730dadcaea5fbc6bb8f1136966ef66
References: git-fixes
Patch-mainline: v5.7-rc7

'es' is malloced from exfat_get_dentry_set() in exfat_find() and should
be freed before leaving from the error handling cases, otherwise it will
cause memory leak.

Fixes: 5f2aa075070c ("exfat: add inode operations")
