Subject: eCryptfs: Swap dput() and mntput()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5366dc9fd1cb74023790a8edf29e4fe42c886dcf;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

eCryptfs: Swap dput() and mntput()

ecryptfs_d_release() is doing a mntput before doing the dput.  This patch
moves the dput before the mntput.

Thanks to Rajouri Jammu for reporting this.
