Subject: [PATCH 2/3] i2c: qup: Remove dev_err() log after platform_get_irq*() failure

The debug message after platform_get_irq() failure is redundant
because platform_get_irq() already prints an error. Thus remove it.

The semantic patch that makes this report is available
in scripts/coccinelle/api/platform_get_irq.cocci.

Found using - http://coccinelle.lip6.fr/

Completely missed that! I will update and resend.

Can a tag like “Generated by: scripts/coccinelle/api/platform_get_irq.cocci”
be more helpful than the other description variant?

How do you think about to omit the curly brackets here after only a single
statement would be used in the if branch?
