Asymmetrical because cascading function names maybe additive for easy reading/recall.

'eal_parse_sysfs_value ==> eal_parse_sysfs_value_<XX> ==> eal_parse_sysfs_value_<XX>_<YY>'

Obviously, this is not a rule - it just makes reading and recalling of cascade easier.
As for:

eal_parse_sysfs_value => eal_parse_sysfs_file_value

inserts an identifier between a name, making it (slightly) difficult to correlate.

Again, as I mentioned earlier, this is subjective argument and matter of (personal!) choice.
