      media: platform: fix some 64-bits warnings · 34b2ea1c
      Mauro Carvalho Chehab authored
      The omap/omap3 and viu drivers are for 32 bit platforms only.
      There, a pointer has 32 bits. Now that those drivers build
      for 64 bits with COMPILE_TEST, they produce the following
      warnings:
      
      drivers/media/platform/omap/omap_vout_vrfb.c: In function 'omap_vout_allocate_vrfb_buffers':
      drivers/media/platform/omap/omap_vout_vrfb.c:57:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

               (__force void __user *)fpc.fpcaddr,
               ^
      
      Add some typecasts to remove those warnings when building for
      64 bits.

      media: atomisp: remove an impossible condition · e935dbfc
      Mauro Carvalho Chehab authored
      Changeset dc9f65cf ("media: staging: atomisp: avoid a warning if 32
      bits build") was meant to solve an impossible condition when building
      with 32 bits. It turns that this impossible condition also happens wit
      64 bits:
      	drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:698 gmin_get_config_var() warn: impossible condition '(*out_len > (~0)) => (0-u64max > u64max)'
      
      After a further analysis, this condition will always be false as, on
      all architectures, size_t doesn't have more bits than unsigned long.
      
      Also, the only two archs that really matter are x86 and x86_64, as this
      driver doesn't build on other archs (as it depends on X86-specific UEFI
      support).
      
      So, just drop the useless code.

      media: v4l2-fwnode: simplify v4l2_fwnode_reference_parse_int_props() · 9879c9d3
      Mauro Carvalho Chehab authored
      The logic at v4l2_fwnode_reference_parse_int_props() is somewhat
      complex and violates Linux coding style, as it does multiple
      statements on a single line. That makes static analyzers to
      be confused, as warned by smatch:
      
      	drivers/media/v4l2-core/v4l2-fwnode.c:832 v4l2_fwnode_reference_parse_int_props() warn: passing zero to 'PTR_ERR'
      
      Simplify the logic, in order to make clearer about what happens
      when v4l2_fwnode_reference_get_int_prop() returns an error.

      media: dvb_frontend: fix locking issues at dvb_frontend_get_event() · 76d81243
      Mauro Carvalho Chehab authored
      As warned by smatch:
      	drivers/media/dvb-core/dvb_frontend.c:314 dvb_frontend_get_event() warn: inconsistent returns 'sem:&fepriv->sem'.
      	  Locked on:   line 288

      	               line 314
      	  Unlocked on: line 303
      
      The lock implementation for get event is wrong, as, if an
      interrupt occurs, down_interruptible() will fail, and the
      routine will call up() twice when userspace calls the ioctl
      again.
      
      The bad code is there since when Linux migrated to git, in
      2005.

      media: isppreview: fix __user annotations · 99ed3dd8
      Mauro Carvalho Chehab authored
      The 'from' variable at preview_config() expects an __user * type.
      
      However, the logic there does:
      
          from = *(void * __user *) ((void *)cfg + attr->config_offset);
      
      With actually means a void pointer, pointing to a void __ user
      pointer. When the first pointer is de-referenced with *(foo),
      the type it returns is "void *" instead of "void __user *".
      
      Change it to:
          from = *(void __user **) ((void *)cfg + attr->config_offset);
      
      in order to obtain, when de-referenced, a void __user pointer,
      as desired.
      
      That prevent those warnings:

      media: vpbe_display: properly handle error case · 693035dc
      Mauro Carvalho Chehab authored
      if v4l2_subdev_call(..., VENC_GET_FLD,...) fails, it
      currently returns a random value. Instead, return 1.
      
      That's probably better than returning 0, as this is very
      likely what happens in practice with the current code, as
      as the probably of an unititialized 32 bits integer to
      have an specific value (0, in this case), is 1/(2^32).
      
      An alternative would be to return an error code, and
      let the caller to hint, based on the past received
      frame, but that sounds weird.

      media: isif: reorder a statement to match coding style · 09821dfd
      Mauro Carvalho Chehab authored
      On all places, we do:
      	void <asn_ref> *foo;
      
      Here, it is doing, instead:
      	void * <asn_ref> foo;
      
      That tricks static analyzers, making it see errors where
      there's none. So, just reorder in order to cleanup those

      media: davinci_vpfe: fix vpfe_ipipe_init() error handling · 3585fdc7
      Mauro Carvalho Chehab authored
      As warned:
      	drivers/staging/media/davinci_vpfe/dm365_ipipe.c:1834 vpfe_ipipe_init() error: we previously assumed 'res' could be null (see line 1797)
      
      There's something wrong at vpfe_ipipe_init():
      
      1) it caches the resourse_size() from from the first region
         and reuses to the second region;
      
      2) the "res" var is overridden 3 times;
      
      3) at free logic, it assumes that "res->start" is not
         overridden by platform_get_resource(pdev, IORESOURCE_MEM, 6),
         but that's not true, as it can even be NULL there.
      
      This patch fixes the above issues by:
      
      a) store the resources used by release_mem_region() on
         a separate var;
      
      b) stop caching resource_size(), using the function where
         needed.

      media: davinci_vpfe: remove useless checks from ipipe · 3d37383b
      Mauro Carvalho Chehab authored
      The dm365_ipipe_hw.c and dm365_ipipe.c file check if several table
      pointers, declared at davinci_vpfe_user.h, are filled before using
      them.
      
      The problem is that those pointers come from struct declarations
      like:
      
      	struct vpfe_ipipe_yee {
      	...
      	short table[VPFE_IPIPE_MAX_SIZE_YEE_LUT];
      	};
