ALSA: usb-audio: qcom: Use PAGE_ALIGN macro for buffer size calculation
Use the kernel's PAGE_ALIGN() macro instead of open-coding the page
alignment calculation. This improves code readability and follows
kernel coding style.
The manual calculation:
mult = len / PAGE_SIZE;
remainder = len % PAGE_SIZE;
len = mult * PAGE_SIZE;
len += remainder ? PAGE_SIZE : 0;
is equivalent to:
len = PAGE_ALIGN(len);
