Hello Dragos,
Your mpc52xx_psc_spi_do_remove() from current git:
| static int __exit mpc52xx_psc_spi_do_remove(struct device *dev)
| {
| struct spi_master *master = dev_get_drvdata(dev);
| struct mpc52xx_psc_spi *mps = spi_master_get_devdata(master);
|
| flush_workqueue(mps->workqueue);
| destroy_workqueue(mps->workqueue);
| spi_unregister_master(master);
| free_irq(mps->irq, mps);
| if (mps->psc)
| iounmap(mps->psc);
|
| return 0;
| }
It looks to me that spi_unregister_master() frees your mps struct and
the following free_irq() and iounmap() touches deallocated memory.
Might this be correct?
Sebastian
