hanzj 36bdf9fb37 drivers/analog/dac7554: Add NULL checks after kmm_malloc in dac7554_initialize 
dac7554_initialize() calls kmm_malloc twice without checking the return
value.  If either allocation fails, the subsequent pointer dereferences
lead to a NULL pointer access and crash.

Add NULL checks for both allocations, following the pattern already used
in mcp3008.c, mcp48xx.c, and mcp47x6.c.  When the second allocation
fails, free the first allocation before returning NULL.
