Subject: [PATCH 70/86] Fix the MSDOS_MBR_MAGIC type, not the format string.
|
|
|
38cfe28 |
|
|
|
38cfe28 |
The value of MSDOS_MBR_MAGIC is 16 bits; make it evaluate that way,
|
|
|
38cfe28 |
instead of promoting it to int for efi_error() formatting.
|
|
|
38cfe28 |
|
|
|
38cfe28 |
Fixes: 3cf3b3d5cf3f6ff7ddb315676e338a0632aa6dc8
