Subject: [PATCH AUTOSEL 5.0 134/262] efi: Fix build error due to enum collision between efi.h and ima.h
From: Anders Roxell <anders.roxell@...aro.org>
[ Upstream commit 5c418dc789a3898717ebf2caa5716ba91a7150b2 ]
The following commit:
a893ea15d764 ("tpm: move tpm_chip definition to include/linux/tpm.h")
introduced a build error when both IMA and EFI are enabled:
In file included from ../security/integrity/ima/ima_fs.c:30:
../security/integrity/ima/ima.h:176:7: error: redeclaration of enumerator "NONE"
What happens is that both headers (ima.h and efi.h) defines the same
'NONE' constant, and it broke when they started getting included from
the same file:
Rework to prefix the EFI enum with 'EFI_*'.
