Browse Source 
Commit changes return value of ipmi_fru_get_adjust_size_from_buffer() from void
to int in order to determine whether call was successful or wasn't.
ipmi_fru_upg_ekeying() got re-work as well.

Changes to ipmi_fru_get_adjust_size_from_buffer():
* CHUNK_SIZE removed
* code formatting
* return value void -> int

Changes to ipmi_fru_upg_ekeying():
* check whether pFilename is NULL
* check return values of called functions
* re-work code - return early on error instead of nested if()
* added (error) messages
