[PATCH 5.14 031/162] misc: genwqe: Fixes DMA mask setting

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

commit 8d753db5c227d1f403c4bc9cae4ae02c862413cd upstream.

Commit 505b08777d78 ("misc: genwqe: Use dma_set_mask_and_coherent to simplify code")
changed the logic in the code.

Instead of a ||, a && should have been used to keep the code the same.

Fixes: 505b08777d78 ("misc: genwqe: Use dma_set_mask_and_coherent to simplify code")
