-Subject: [PATCH] brcmfmac: validate user provided data for memdump before
- copying
-
-In patch "brcmfmac: add support for sysfs initiated coredump", a new
-scenario of brcmf_debug_create_memdump was added in which the user of
-the function might not necessarily provide prefix data. Hence the
-function should not assume the data is always valid and should perform a
-check before copying.
