This change will break exit_put error path.
I think kfree will be called from txx9_device_release by put_device.
Please refer James's comment on previous trial:
<https://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=20180305221833.GJ4197%40saruman>
yes, put_device will call txx9_device_release and free txx9_sramc_dev,
and kfree in sysfs_create_bin_file() error handle
is also unneeded, I will send a new patch soon
