tracing/fastboot: fix len of func buffer (8001530d) · Commits · e / devices / android_kernel_teracube_mt6765

Impact: fix possible stack overrun This is a port of a patch included in the mainline (KSYM_SYMBOL_LEN fixes). The current func len is not large enough to contain the max symbol len, the right size must be KSYM_SYMBOL_LEN. Signed-off-by:
