The following smatch error was introduced by commit 7ca5f6be7900 ("i2c:
recovery: add get_bus_free callback"):
drivers/i2c/i2c-core-base.c:228 i2c_generic_scl_recovery() error: uninitialized symbol 'ret'.
Analysis of the code appears to show that the smatch error is a false
positive since 'ret' will in fact be initialized after exiting the
'while()' loop.
Squelch the smatch error since it is a false positive.
Fixes: 7ca5f6be7900 ("i2c: recovery: add get_bus_free callback")
