pxa168fb: Fix the function used to release some memory in an error handling path
[ Upstream commit 3c911fe799d1c338d94b78e7182ad452c37af897 ]
In the probe function, some resources are allocated using 'dma_alloc_wc()',
they should be released with 'dma_free_wc()', not 'dma_free_coherent()'.
We already use 'dma_free_wc()' in the remove function, but not in the
error handling path of the probe function.
Also, remove a useless 'PAGE_ALIGN()'. 'info->fix.smem_len' is already
PAGE_ALIGNed.
Fixes: 638772c7553f ("fb: add support of LCD display controller on pxa168/910 (base layer)")
