When something goes wrong, platform_get_irq() will print an error message, so in order to avoid the situation of repeat output,we should remove dev_err here. Changes form v3: - fix the theme writing error. Changes from v2: - modify the theme format and content description. - reformat the patch, it's the wrong way to resubmit a new patch that should be modified on top of the original. The original piece is: https://lore.kernel.org/patchwork/patch/1219611/ Changes from v1: - the title has changed, because the description is not very detailed. - the code has been modified, because it needs to match the theme.
