From 712401bc77ff1836855775d74a6bfaf49ab320f9 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 30 Apr 2018 15:51:38 -0700 Subject: [PATCH] fscrypt: remove error messages for skcipher_request_alloc() failure skcipher_request_alloc() can only fail due to lack of memory, and in that case the memory allocator will have already printed a detailed error message. Thus, remove the redundant error messages from fscrypt.
