* diva, sedlbauer: the 'ready' label is only used in certain configurations * hfc_pci: - cast 'arg' to proper size for testing and printing - print out 'void __iomem *' variables with %p, rather than using incorrect casts that throw warnings Signed-off-by:

There's a potential problem in isdn_ppp.c::isdn_ppp_decompress(). dev_alloc_skb() may fail and return NULL. If it does we will be passing a NULL skb_out to ipc->decompress() and may also end up dereferencing a NULL pointer at *proto = isdn_ppp_strip_proto(skb_out); Correct this by testing 'skb_out' against NULL early and bail out.

- remove cvs rcsid and alter code that uses it. - allow a semicolon after use of macro to not confuse parsers (e.g. indent) by do {} while (0) - JIFFIES_DIFF is simple subtraction, subtract directly - returns cleanup -- do not put values in parenthesis and do not return nothing at the end of void functions - comments are /* */ in C (not //) Signed-off-by: -

make the code indented by tabs. Signed-off-by:
-
Jiri Slaby authored
Save 3 indent levels in interrupt routine by moving the code to a separate function. This needs to be done to allow Lindent do its work, since only 4 columns are used for indenting now and hence Lindent makes a big mess in the code, when moves it 4*5 columns to the right. Signed-off-by:

register tty device dynamically according to the count of board ports. Signed-off-by:

Jiri Slaby authored
Reorganizate module init and exit and implement logic, when something fails in these functions. The former is needed for proper handling dynamic tty_register_device. Signed-off-by:

Let's have these function at the end of the driver and expand stli_init directly into module_init fucntion, since there is nothing other to have there. Signed-off-by:

Check more retvals and react somehow. Signed-off-by:

Jiri Slaby authored
Only ISA cards should be freed in module exit. Pci probed are freed in pci_remove. Define a flag, where we store this info a what to check against. Signed-off-by:

- remove unneeded license text - remove functions, that are implemented in kernel -- call them (strtoul, min, tolower) - do not cast NULL - there is no static table, throw away code, which takes care of it -- find module param cards in that place instead. Signed-off-by:

Use probing for pci devices. Change some __inits to __devinits to use these functions in probe function. Create stli_cleanup_ports and move there cleanup code from module_exit() code to not have duplicite cleanup code. Signed-off-by:

Use dynamic tty device registering depending on board's port count. (i -> retval change is relevant, since gcc complains about signedness of i) Signed-off-by:

Release everything what was allocated and check return value of isa probing. Release only ISA boards in module exit, since pci have their own pci-probing-remove. Signed-off-by:
