Reported by checkpatch:
CHECK: Macro argument 'gcam' may be better as '(gcam)' to avoid
precedence issues
Disambiguates '&' (address-of) operator and '->' operator precedence,
accounting for how '(gcam)->bundle->dev' is a 'struct device' and not a
'struct device*', which is required by the dev_{dbg,info,err} driver
model diagnostic macros. Issue found by checkpatch.
