Hi,

I thought it would be harder to debug/fix. Please find attached a patch
that corrects this boot issue, the exynos5 i2c driver was still using
the "spinlock_t" structure and all initial utility functions, I just
changed it to use the "raw_spinlock_t" struct.

Was it the good fix?

Best,

Benjamin Rouxel.
