[PATCH] uio: fsl_elbc_gpcm: preserve platform_get_irq() errors

[Diego Fernando Mancera Gomez]

In uio_fsl_elbc_gpcm_probe(), platform_get_irq() returns a negative errno
on failure. Because irq is declared as unsigned int, the error check
if (irq < 0) is never satisfied and negative error codes (such as
-EPROBE_DEFER) bypass the error handling.

Change the local irq declaration from unsigned int to int so negative
errors from platform_get_irq() reach the error check and are properly
returned.
