Subject: crypto: jitterentropy - use safe format string parameters
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0c5f0aa5dd92a36a2c6491695abcb95196b88ef6;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

crypto: jitterentropy - use safe format string parameters

Since the API for jent_panic() does not include format string parameters,
adjust the call to panic() to use a literal string to avoid any future
callers from leaking format strings into the panic message.
