Hi Thanks for your response! No, it does not sound like it's worth changing anything. Although in the worst case with this patch you probably have a more consistent error :) Best regards Rickard Strandqvist 2014-06-02 9:48 GMT+02:00 Christian König <deathsimple@vodafone.de>: > Am 01.06.2014 01:10, schrieb Rickard Strandqvist: > >> There is a risk that the variable will be used without being initialized. >> >> This was largely found by using a static code analysis program called >> cppcheck. >> >> Signed-off-by: Rickard Strandqvist >> <rickard_strandqvist@spectrumdigital.se> > > > On the one hand it looks like a valid fix to me, but on the other hand the > r600_cp.c code is deprecated for something like five years now. > > I would like to avoid touching it in any way and just let it rest peacefully > until we can remove it entirely. > > Christian. > > >> --- >> drivers/gpu/drm/radeon/r600_cp.c | 2 +- >> 1 file changed, 1 insertion(+), 1 deletion(-) >> >> diff --git a/drivers/gpu/drm/radeon/r600_cp.c >> b/drivers/gpu/drm/radeon/r600_cp.c >> index 8c9b7e2..0770ad6 100644 >> --- a/drivers/gpu/drm/radeon/r600_cp.c >> +++ b/drivers/gpu/drm/radeon/r600_cp.c >> @@ -2615,7 +2615,7 @@ int r600_cs_legacy_ioctl(struct drm_device *dev, >> void *data, struct drm_file *fp >> struct drm_radeon_cs *cs = data; >> struct drm_buf *buf; >> unsigned family; >> - int l, r = 0; >> + int l = 0, r = 0; >> u32 *ib, cs_id = 0; >> if (dev_priv == NULL) { > >

There is a risk that the variable will be used without being initialized. This was largely found by using a static code analysis program called cppcheck.
