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.
