Atsushi Nemoto f1c582154e i2c: altera: Fix race between xfer_msg and isr thread ... [ Upstream commit 5d4c797749 ] Use a mutex to protect access to idev->msg_len, idev->buf, etc. which are modified by both altr_i2c_xfer_msg() and altr_i2c_isr(). This is the minimal fix for easy backporting. A cleanup to remove the spinlock will be added later.
