fbdev: arcfb: Fix error handling in arcfb_probe()
[ Upstream commit 5a6bef7 ] Smatch complains that: arcfb_probe() warn: 'irq' from request_irq() not released on lines: 587. Fix error handling in the arcfb_probe() function. If IO addresses are not provided or framebuffer registration fails, the code will jump to the err_addr or err_register_fb label to release resources. If IRQ request fails, previously allocated resources will be freed.
