From cbe46408b666983284e8be290950d526dbc0f0a4 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Wed, 9 Jan 2008 02:08:16 +0300 Subject: [PATCH 26/64] I don't think we should check for IRQs when determining which one of power supplies to register. Better use is_{ac,usb}_online callbacks, this will not produce an obstacle to implement polling -- when irqs aren't mandatory. I'll send my two pending patches to show the idea. For this particular issue, I think something like that should work. If it works for you, I'll commit that version, preserving your authorship, of course. --- drivers/power/pda_power.c | 80 ++++++++++++++++++++++++-------------------- 1 files changed, 44 insertions(+), 36 deletions(-) diff --git a/drivers/power/pda_power.c b/drivers/power/pda_power.c index c058f28..d98622f 100644 --- a/drivers/power/pda_power.c +++ b/drivers/power/pda_power.c @@ -168,66 +168,74 @@ static int pda_power_probe(struct platform_device *pdev) pda_power_supplies[1].num_supplicants = pdata->num_supplicants; } - ret = power_supply_register(&pdev->dev, &pda_power_supplies[0]); - if (ret) { - dev_err(dev, "failed to register %s power supply\n", - pda_power_supplies[0].name); - goto supply0_failed; - } + if (pdata->is_ac_online) { + ret = power_supply_register(&pdev->dev, &pda_power_supplies[0]); + if (ret) { + dev_err(dev, "failed to register %s power supply\n", + pda_power_supplies[0].name); + goto ac_supply_failed; + } - ret = power_supply_register(&pdev->dev, &pda_power_supplies[1]); - if (ret) { - dev_err(dev, "failed to register %s power supply\n", - pda_power_supplies[1].name); - goto supply1_failed; + if (ac_irq) { + ret = request_irq(ac_irq->start, power_changed_isr, + get_irq_flags(ac_irq), ac_irq->name, + &pda_power_supplies[0]); + if (ret) { + dev_err(dev, "request ac irq failed\n"); + goto ac_irq_failed; + } + } } - if (ac_irq) { - ret = request_irq(ac_irq->start, power_changed_isr, - get_irq_flags(ac_irq), ac_irq->name, - &pda_power_supplies[0]); + if (pdata->is_usb_online) { + ret = power_supply_register(&pdev->dev, &pda_power_supplies[1]); if (ret) { - dev_err(dev, "request ac irq failed\n"); - goto ac_irq_failed; + dev_err(dev, "failed to register %s power supply\n", + pda_power_supplies[1].name); + goto usb_supply_failed; } - } - if (usb_irq) { - ret = request_irq(usb_irq->start, power_changed_isr, - get_irq_flags(usb_irq), usb_irq->name, - &pda_power_supplies[1]); - if (ret) { - dev_err(dev, "request usb irq failed\n"); - goto usb_irq_failed; + if (usb_irq) { + ret = request_irq(usb_irq->start, power_changed_isr, + get_irq_flags(usb_irq), + usb_irq->name, + &pda_power_supplies[1]); + if (ret) { + dev_err(dev, "request usb irq failed\n"); + goto usb_irq_failed; + } } } - goto success; + return 0; usb_irq_failed: - if (ac_irq) + if (pdata->is_usb_online) + power_supply_unregister(&pda_power_supplies[1]); +usb_supply_failed: + if (pdata->is_ac_online && ac_irq) free_irq(ac_irq->start, &pda_power_supplies[0]); ac_irq_failed: - power_supply_unregister(&pda_power_supplies[1]); -supply1_failed: - power_supply_unregister(&pda_power_supplies[0]); -supply0_failed: + if (pdata->is_ac_online) + power_supply_unregister(&pda_power_supplies[0]); +ac_supply_failed: noirqs: wrongid: -success: return ret; } static int pda_power_remove(struct platform_device *pdev) { - if (usb_irq) + if (pdata->is_usb_online && usb_irq) free_irq(usb_irq->start, &pda_power_supplies[1]); - if (ac_irq) + if (pdata->is_ac_online && ac_irq) free_irq(ac_irq->start, &pda_power_supplies[0]); del_timer_sync(&charger_timer); del_timer_sync(&supply_timer); - power_supply_unregister(&pda_power_supplies[1]); - power_supply_unregister(&pda_power_supplies[0]); + if (pdata->is_usb_online) + power_supply_unregister(&pda_power_supplies[1]); + if (pdata->is_ac_online) + power_supply_unregister(&pda_power_supplies[0]); return 0; } -- 1.5.3.8
