Dan Carpenter 5bcc37dc24 eeprom: idt_89hpesx: uninitialized data in idt_dbgfs_csr_write()
[ Upstream commit 71d46f1ff2 ]

The simple_write_to_buffer() function will return positive/success if it
is able to write a single byte anywhere within the buffer.  However that
potentially leaves a lot of the buffer uninitialized.

In this code it's better to return 0 if the offset is non-zero.  This
code is not written to support partial writes.  And then return -EFAULT
if the buffer is not completely initialized.

Fixes: cfad642538 ("eeprom: Add IDT 89HPESx EEPROM/CSR driver")
