Subject: i2c: exynos5: don't check for irq 0
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5df324b5f4baa3a51990f078fa445800197dfba3;p=linux.git

i2c: exynos5: don't check for irq 0

platform_get_irq never returns 0. Don't check for this. Make it clear that
the error path always returns a negative error code.
