Hi, here is a patch series fixing I2C drivers which free their private data structure and leave the clientdata pointer dangling or do the cleanup in the wrong order. All occurences were found using coccinelle [1] and the semantic patch below. The matches have been reviewed, and sometimes adapted. The complete series goes to linux-i2c and kernel-janitors. The rest of the CCs is handled per patch using get_maintainers.pl (which always adds LKML, so you have the complete series there, too). Please review, comment, apply! Kind regards, Wolfram [1] http://coccinelle.lip6.fr/ === @@ type T; identifier client, data; @@ // Check if function uses clientdata ( i2c_set_clientdata(client, data); | data = i2c_get_clientdata(client); | T data = i2c_get_clientdata(client); ) // Anything inbetween ... // Check if clientdata gets NULLed before data is freed ( i2c_set_clientdata(client, NULL); ... kfree(data); | + i2c_set_clientdata(client, NULL); kfree(data); ... - i2c_set_clientdata(client, NULL); | + i2c_set_clientdata(client, NULL); ? kfree(data); ) === drivers/gpio/adp5588-gpio.c | 1 + drivers/gpio/max732x.c | 1 + drivers/gpio/pca953x.c | 1 + drivers/gpio/pcf857x.c | 7 ++++--- drivers/hwmon/ad7414.c | 2 ++ drivers/hwmon/ad7418.c | 2 ++ drivers/hwmon/adm1021.c | 2 ++ drivers/hwmon/adm1025.c | 2 ++ drivers/hwmon/adm1026.c | 2 ++ drivers/hwmon/adm1029.c | 2 ++ drivers/hwmon/adm1031.c | 2 ++ drivers/hwmon/adm9240.c | 2 ++ drivers/hwmon/ads7828.c | 5 ++++- drivers/hwmon/adt7462.c | 2 ++ drivers/hwmon/adt7470.c | 2 ++ drivers/hwmon/adt7475.c | 2 ++ drivers/hwmon/amc6821.c | 2 ++ drivers/hwmon/asb100.c | 2 ++ drivers/hwmon/atxp1.c | 2 ++ drivers/hwmon/dme1737.c | 2 ++ drivers/hwmon/ds1621.c | 2 ++ drivers/hwmon/f75375s.c | 4 ++-- drivers/hwmon/g760a.c | 4 ++-- drivers/hwmon/gl518sm.c | 2 ++ drivers/hwmon/gl520sm.c | 2 ++ drivers/hwmon/lm63.c | 2 ++ drivers/hwmon/lm77.c | 2 ++ drivers/hwmon/lm78.c | 2 ++ drivers/hwmon/lm80.c | 2 ++ drivers/hwmon/lm83.c | 2 ++ drivers/hwmon/lm85.c | 2 ++ drivers/hwmon/lm87.c | 2 ++ drivers/hwmon/lm90.c | 2 ++ drivers/hwmon/lm92.c | 2 ++ drivers/hwmon/lm93.c | 2 ++ drivers/hwmon/lm95241.c | 1 + drivers/hwmon/ltc4215.c | 2 ++ drivers/hwmon/ltc4245.c | 2 ++ drivers/hwmon/max1619.c | 2 ++ drivers/hwmon/max6650.c | 2 ++ drivers/hwmon/pcf8591.c | 6 +++++- drivers/hwmon/smsc47m192.c | 2 ++ drivers/hwmon/thmc50.c | 2 ++ drivers/hwmon/tmp401.c | 1 + drivers/hwmon/w83791d.c | 2 ++ drivers/hwmon/w83792d.c | 2 ++ drivers/hwmon/w83793.c | 1 + drivers/hwmon/w83l785ts.c | 2 ++ drivers/hwmon/w83l786ng.c | 2 ++ drivers/input/keyboard/lm8323.c | 2 ++ drivers/input/keyboard/qt2160.c | 2 +- drivers/input/touchscreen/mcs5000_ts.c | 2 +- drivers/input/touchscreen/tsc2007.c | 1 + drivers/leds/leds-lp3944.c | 2 +- drivers/leds/leds-pca9532.c | 4 ++-- drivers/leds/leds-pca955x.c | 4 ++-- drivers/macintosh/therm_adt746x.c | 2 ++ drivers/media/radio/radio-tea5764.c | 2 ++ drivers/media/radio/si470x/radio-si470x-i2c.c | 2 +- drivers/media/video/cs5345.c | 1 + drivers/media/video/cs53l32a.c | 1 + drivers/media/video/ir-kbd-i2c.c | 2 ++ drivers/media/video/tda9840.c | 1 + drivers/media/video/tea6415c.c | 1 + drivers/media/video/tea6420.c | 1 + drivers/media/video/ths7303.c | 1 + drivers/mfd/88pm860x-i2c.c | 1 + drivers/mfd/ab3100-core.c | 2 ++ drivers/mfd/da903x.c | 1 + drivers/mfd/menelaus.c | 3 ++- drivers/mfd/pcf50633-core.c | 1 + drivers/mfd/tps65010.c | 2 +- drivers/mfd/wm8350-i2c.c | 2 ++ drivers/misc/ad525x_dpot.c | 2 +- drivers/misc/eeprom/at24.c | 2 +- drivers/misc/eeprom/eeprom.c | 6 +++++- drivers/misc/eeprom/max6875.c | 2 ++ drivers/misc/ics932s401.c | 2 ++ drivers/misc/isl29003.c | 6 +++++- drivers/misc/tsl2550.c | 6 +++++- drivers/mtd/maps/pismo.c | 8 +++++++- drivers/power/bq27x00_battery.c | 2 ++ drivers/power/ds2782_battery.c | 4 ++-- drivers/regulator/max1586.c | 2 +- drivers/regulator/max8649.c | 3 ++- drivers/regulator/max8660.c | 2 +- drivers/rtc/rtc-ds1307.c | 2 ++ drivers/rtc/rtc-fm3130.c | 2 ++ drivers/rtc/rtc-m41t80.c | 2 ++ drivers/rtc/rtc-pcf8563.c | 2 ++ drivers/rtc/rtc-pcf8583.c | 2 ++ drivers/rtc/rtc-rs5c372.c | 2 ++ drivers/rtc/rtc-s35390a.c | 4 ++-- drivers/staging/dream/synaptics_i2c_rmi.c | 2 ++ drivers/staging/go7007/wis-saa7113.c | 1 + drivers/staging/go7007/wis-saa7115.c | 1 + drivers/staging/go7007/wis-tw9903.c | 1 + drivers/staging/iio/adc/max1363_core.c | 2 ++ drivers/staging/iio/light/tsl2563.c | 2 ++ drivers/usb/otg/isp1301_omap.c | 5 ++++- drivers/video/matrox/matroxfb_maven.c | 1 + drivers/w1/masters/ds2482.c | 2 ++ 102 files changed, 198 insertions(+), 33 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
