>From 3a54e6872e220e1ac4db0eae126a20b5383dae3e Mon Sep 17 00:00:00 2001 From: Jeremy Compostella Date: Tue, 10 May 2016 10:34:21 +0200 Subject: [PATCH] efibc: report more information in the error messages Report the name of the EFI variable if the value size is too large or if efibc_set_variable() fails to allocate the struct efivar_entry object. If efibc_set_variable() fails because the value size is too large, it also reports the value size in the error message.
