Message-Id: <1354753251-27561-1-git-send-email-peterhuewe@gmx.de> Date: Thu, 6 Dec 2012 01:20:51 +0100 From: Peter Huewe <peterhuewe@....de> To: Kent Yoder <key@...ux.vnet.ibm.com> Cc: Peter Huewe <PeterHuewe@....de>, Mathias LEBLANC <Mathias.LEBLANC@...com>, Jean-Luc BLANC <jean-luc.blanc@...com>, "Sirrix@...per.es" <Sirrix@...per.es>, linux-kernel@...r.kernel.org, Rajiv Andrade <mail@...jiv.net>, "tpmdd-devel@...ts.sourceforge.net" <tpmdd-devel@...ts.sourceforge.net>, Kent Yoder <shpedoikal@...il.com>, Peter Huewe <peterhuewe@....de> Subject: [PATCH] char/tpm: Use struct dev_pm_ops for power management This patch converts the suspend and resume functions for tpm_i2c_stm_st33 to the new dev_pm_ops. Signed-off-by: Peter Huewe <peterhuewe@....de> --- Note: I'm sending this patch on behalf of myself only and nobody else, especially not my employer - and I'm doing this in my spare time. I have to inform you that I'm working for a direct competitor of the driver author, but I'm not using any knowledge that is considered secret in any way. I have a personal interest in the TPM subsystem and want to keep it as clean as possible. drivers/char/tpm/tpm_i2c_stm_st33.c | 25 ++++++++++--------------- 1 files changed, 10 insertions(+), 15 deletions(-) diff --git a/drivers/char/tpm/tpm_i2c_stm_st33.c b/drivers/char/tpm/tpm_i2c_stm_st33.c index b11201f..ecbb81e 100644 --- a/drivers/char/tpm/tpm_i2c_stm_st33.c +++ b/drivers/char/tpm/tpm_i2c_stm_st33.c @@ -826,12 +826,10 @@ static __devexit int tpm_st33_i2c_remove(struct i2c_client *client) * @param: mesg, the power management message. * @return: 0 in case of success. */ -static int tpm_st33_i2c_pm_suspend(struct i2c_client *client, pm_message_t mesg) +static int tpm_st33_i2c_pm_suspend(struct device *dev) { - struct tpm_chip *chip = - (struct tpm_chip *)i2c_get_clientdata(client); - struct st33zp24_platform_data *pin_infos = - ((struct i2c_client *)TPM_VPRIV(chip))->dev.platform_data; + struct tpm_chip *chip = dev_get_drvdata(dev); + struct st33zp24_platform_data *pin_infos = dev->platform_data; int ret = 0; if (power_mgt) @@ -839,7 +837,7 @@ static int tpm_st33_i2c_pm_suspend(struct i2c_client *client, pm_message_t mesg) else{ if (chip->data_buffer == NULL) chip->data_buffer = pin_infos->tpm_i2c_buffer[0]; - ret = tpm_pm_suspend(&client->dev); + ret = tpm_pm_suspend(dev); } return ret; } /* tpm_st33_i2c_suspend() */ @@ -849,12 +847,10 @@ static int tpm_st33_i2c_pm_suspend(struct i2c_client *client, pm_message_t mesg) * @param: client, the i2c_client drescription (TPM I2C description). * @return: 0 in case of success. */ -static int tpm_st33_i2c_pm_resume(struct i2c_client *client) +static int tpm_st33_i2c_pm_resume(struct device *dev) { - struct tpm_chip *chip = - (struct tpm_chip *)i2c_get_clientdata(client); - struct st33zp24_platform_data *pin_infos = - ((struct i2c_client *)TPM_VPRIV(chip))->dev.platform_data; + struct tpm_chip *chip = dev_get_drvdata(dev); + struct st33zp24_platform_data *pin_infos = dev->platform_data; int ret = 0; @@ -867,7 +863,7 @@ static int tpm_st33_i2c_pm_resume(struct i2c_client *client) } else{ if (chip->data_buffer == NULL) chip->data_buffer = pin_infos->tpm_i2c_buffer[0]; - ret = tpm_pm_resume(&client->dev); + ret = tpm_pm_resume(dev); if (!ret) tpm_do_selftest(chip); } @@ -880,16 +876,15 @@ static const struct i2c_device_id tpm_st33_i2c_id[] = { }; MODULE_DEVICE_TABLE(i2c, tpm_st33_i2c_id); - +static SIMPLE_DEV_PM_OPS(tpm_st33_i2c_ops, tpm_st33_i2c_pm_suspend, tpm_st33_i2c_pm_resume); static struct i2c_driver tpm_st33_i2c_driver = { .driver = { .owner = THIS_MODULE, .name = TPM_ST33_I2C, + .pm = &tpm_st33_i2c_ops, }, .probe = tpm_st33_i2c_probe, .remove = tpm_st33_i2c_remove, - .resume = tpm_st33_i2c_pm_resume, - .suspend = tpm_st33_i2c_pm_suspend, .id_table = tpm_st33_i2c_id }; -- 1.7.8.6 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
