/*
* linux/drivers/message/fusion/mptctl.c
- * Fusion MPT misc device (ioctl) driver.
- * For use with PCI chip/adapter(s):
- * LSIFC9xx/LSI409xx Fibre Channel
+ * mpt Ioctl driver.
+ * For use with LSI Logic PCI chip/adapters
* running LSI Logic Fusion MPT (Message Passing Technology) firmware.
*
- * Credits:
- * This driver would not exist if not for Alan Cox's development
- * of the linux i2o driver.
- *
- * A special thanks to Pamela Delaney (LSI Logic) for tons of work
- * and countless enhancements while adding support for the 1030
- * chip family. Pam has been instrumental in the development of
- * of the 2.xx.xx series fusion drivers, and her contributions are
- * far too numerous to hope to list in one place.
- *
- * A huge debt of gratitude is owed to David S. Miller (DaveM)
- * for fixing much of the stupid and broken stuff in the early
- * driver while porting to sparc64 platform. THANK YOU!
- *
- * A big THANKS to Eddie C. Dost for fixing the ioctl path
- * and most importantly f/w download on sparc64 platform!
- * (plus Eddie's other helpful hints and insights)
- *
- * Thanks to Arnaldo Carvalho de Melo for finding and patching
- * a potential memory leak in mptctl_do_fw_download(),
- * and for some kmalloc insight:-)
