Subject: USB: gadget: amd5536udc.c: Remove double test
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0cf7a6338808d702c256778188516a16805e6145;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

USB: gadget: amd5536udc.c: Remove double test

The same expression is tested twice and the result is the same each time.
Instead test for use_dma_ppb as in the test above.

The sematic match that finds this problem is as follows:

// <smpl>

(
* E
  || ... || E
|
* E
  && ... && E
)
// </smpl>
