fbdev: viafb: fix typo in hw_bitblt_1 and hw_bitblt_2

2024-04-13T10:51:39+00:00

[ Upstream commit bc87bb342f106a0402186bcb588fcbe945dced4b ]

There are some actions with value 'tmp' but 'dst_addr' is checked instead.
It is obvious that a copy-paste error was made here and the value
of variable 'tmp' should be checked here.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

via_core_init() won't exit the driver when pci_register_driver() failed.
Exit the viafb-i2c and the viafb-gpio in failed path to prevent error.

This is dead code since 3.15. If there is no plan to use
it further, this can be removed forever.

video: fbdev: don't print error message on framebuffer_alloc() failure

2019-06-28T10:30:08+00:00

framebuffer_alloc() can fail only on kzalloc() memory allocation
failure and since kzalloc() will print error message in such case
we can omit printing extra error message in drivers (which BTW is
what the majority of framebuffer_alloc() users is doing already).
