| Subject: x86/microcode/amd: Cache builtin microcode too |
| |
| From: Thomas Gleixner <tglx@linutronix.de> |
| |
| commit d419d28261e72e1c9ec418711b3da41df2265139 upstream |
| |
| save_microcode_in_initrd_amd() fails to cache builtin microcode and only |
| scans initrd. |
| |
| Use find_blobs_in_containers() instead which covers both. |
