Hi Markus, Thanks for your comments. No real fix, as normally , we should return a negative code, In function h8300_8timer_init(), it set ' ret = -EINVAL ', ' ret = ENXIO' , it should be align with a negative code static int __init h8300_8timer_init(struct device_node *node) { ret = ENXIO; <<< base = of_iomap(node, 0); if (!base) { pr_err("failed to map registers for clockevent\n"); goto free_clk; } ret = -EINVAL; <<< irq = irq_of_parse_and_map(node, 0); if (!irq) { pr_err("failed to get irq for clockevent\n"); goto unmap_reg; } -----Original Message----- From: Markus Elfring [mailto:Marku****@web*****] Sent: Tuesday, September 01, 2020 10:46 PM To: tianxianting (RD) <tian.****@h3c*****>; uclin****@lists***** Cc: linux****@vger*****; kerne****@vger*****; Daniel Lezcano <danie****@linar*****>; Thomas Gleixner <tglx****@linut*****>; Yoshinori Sato <ysato****@users*****> Subject: Re: [PATCH] clocksource: Return negative error code in h8300_8timer_init() > A negative error code should be returned * Can an other imperative wording become helpful for the change description? * Would you like to add the tag “Fixes” to the commit message?
