Chengfeng Ye 2518fdc268 i2c: bcm-iproc: Fix bcm_iproc_i2c_isr deadlock issue ... BugLink: https://bugs.launchpad.net/bugs/2039440 commit 4caf4cb1eaed469742ef719f2cc024b1ec3fa9e6 upstream. iproc_i2c_rd_reg() and iproc_i2c_wr_reg() are called from both interrupt context (e.g. bcm_iproc_i2c_isr) and process context (e.g. bcm_iproc_i2c_suspend). Therefore, interrupts should be disabled to avoid potential deadlock. To prevent this scenario, use spin_lock_irqsave().
