Subject: [PATCH 5.2 012/124] scripts/decode_stacktrace: match basepath using shell prefix operator, not regex
From: Nicolas Boichat <drinkcat@...omium.org>
commit 31013836a71e07751a6827f9d2ad41ef502ddaff upstream.
The basepath may contain special characters, which would confuse the regex
matcher. ${var#prefix} does the right thing.

Fixes: 67a28de47faa8358 ("scripts/decode_stacktrace: only strip base path when a prefix of the path")
