Subject: [PATCH] Remove a number of "dead" config variables.
Remove Kconfig entries (and some documentation) for apparently
"dead" config variables.
Signed-off-by: Robert P. J. Day <rpjday@...dspring.com>
---
A script I threw together identified the following as apparently
useless config variables. By "useless," I mean that they:
1) aren't consulted by any Makefile
2) aren't checked by any source or header file
3) don't further select any Kconfig settings
etc. In short, they don't seem to be able to affect the build in any
way.
The variables that are being removed:
USB_SERIAL_SAFE_PADDED
AEDSP16_MPU401
X86_XADD
PARIDE_PARPORT
AIC7XXX_PROBE_EISA_VL
AIC79XX_ENABLE_RD_STRM
SCSI_NCR53C8XX_PROFILE
53C700_IO_MAPPED
ZISOFS_FS
DLCI_COUNT
MOUSE_ATIXL
LCD_DEVICE
The removal was compile tested based on "make allyesconfig". If any
of these variables are still being used in some way, they are keeping
it very well hidden.
