Subject: [PATCH -next] staging: media: Remove surplus dev_err() when using platform_get_irq()

There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq()
or platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.

./drivers/staging/media/sunxi/sun6i-isp/sun6i_isp.c:390:2-9: line 390 is redundant because platform_get_irq() already prints an error
