CLK_GET_RATE_NOCACHE depends on CONFIG_COMMON_CLK. Importing constants.py
when CONFIG_COMMON_CLK is not defined causes:
(gdb) lx-symbols
(...)
File "scripts/gdb/linux/proc.py", line 15, in <module>
from linux import constants
File "scripts/gdb/linux/constants.py", line 2, in <module>
LX_CLK_GET_RATE_NOCACHE = gdb.parse_and_eval("CLK_GET_RATE_NOCACHE")
gdb.error: No symbol "CLK_GET_RATE_NOCACHE" in current context.
