coccinelle: api: add spatch to prevent unnecessary .owner

2014-11-06T23:16:02+00:00

There are calls which silently set the owner of a module. This is the preferred way [1], so avoid setting it manually. Currently, we only care about platform drivers, but there might be more calls to be added later. [1] https://lkml.org/lkml/2014/10/12/87 Signed-off-by: Wolfram Sang Signed-off-by: Greg Kroah-Hartman

coccinelle: misc: semantic patch to delete overly complex return code processing

2014-09-26T11:42:31+00:00

This semantic patch simplifies cases where the effect of the processing of a function call's return code is just to return the result of the function directly. It may also delete a local return flag variable, if this is no longer used. This was proposed by Uwe Kleine-König. Signed-off-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: Script to replace if and BUG with BUG_ON

2014-08-06T10:10:17+00:00

This script detects cases where BUG() follows an if condition on an expression and replaces the if condition and BUG() with a BUG_ON having the conditional expression of the if statement as argument. Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: Script to detect incorrect argument to sizeof

2014-08-06T10:10:17+00:00

This makes an effort to find cases where the argument to sizeof is wrong in memory allocation functions by checking the type of the allocated memory when it is a double pointer and ensuring the sizeof argument takes a pointer to the the memory being allocated. There are false positives in cases the sizeof argument is not used in constructing the return value. Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: Script to use ARRAY_SIZE instead of division of two sizeofs

2014-08-06T10:10:17+00:00

This script detects cases where ARRAY_SIZE can be used such as where there is a division of sizeof the array by the sizeof its first element or by any indexed element or the element type. It replaces the division of the two sizeofs by ARRAY_SIZE. Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: Michal Marek
