[PATCH] Input: cyttsp4 - Fix error on calculating memory size passed to krealloc.

There are several places to perform subtraction to calculate buffer size such as: si->si_ofs.cydata_size = si->si_ofs.test_ofs - si->si_ofs.cydata_ofs; ... p = krealloc(si->si_ptrs.cydata, si->si_ofs.cydata_size, GFP_KERNEL); Actually, data types of above variables during subtraction are size_t,

[PATCH 1/2 ] Add support LZO in cramfs

This is a kernel patch to add support LZO compression in cramfs. I used LZO kernel library patch done by Richard Purdie [EMAIL PROTECTED], and my cramfs patch requires his LZO library patch. Richard's LZO kernel library patch can be found at: http://lwn.net/Articles/238723/ This patch is generate

[PATCH 2/2 ] Add support LZO in mkcramfs tool

This patch adds support LZO compression in mkcramfs tool, so it can generate a cramfs image compress with LZO. To compile mkcramfs with this patch, liblzo2-dev package must be installed. The patch is created against mkcramfs tool ver 1.1 which can be found at: http://sourceforge.net/projects/cramf
