Re: [PATCH] staging: dgap: fix memory leak in dgap_parsefile()

2015-10-01 Thread Ronit Halder

I agree on your point.
But we have to make different mechanism for that and my patch is only
to fix the current code.

[PATCH] staging: dgap: fix memory leak in dgap_parsefile()

2015-09-30 Thread Ronit Halder 
In dgap_parsefile() char pointers are set with kstrdup()
without checking that some string is allocated to that
char pointer before. This patch frees the memory if already allocated
and then set the poniter with kstrdup().

Re: [PATCH] staging: dgap: fix memory leak in dgap_parsefile()

2015-09-30 Thread Ronit Halder 
The existing dgap_parsefile() rejects invalid config file.
But before we know that config file is invalid a lot of memory leak
can happen. Removing the chances of memory leak won't heart anyone.

git-apply shows no error if I apply second patch on

Re: [PATCH] Staging: fbtft: Fix iomem dereference

2015-08-18 Thread Ronit Halder 
Yes, it is not I/O memory address. I was wrong on that.
But it makes sparse happy.
Is here any side effect of using ioread16() ?

regards,
ronit

 Are these really iomem pointers?  A lot of drivers use a fake
 screen_base which is just a buffer of normal memory.
