Claude review: Re: [PATCH v2] staging: fbtft: fb_ra8875: replace udelays with fsleep

Patch Review

**Status**: Looks good.

The v2 patch correctly uses `fsleep(100)` which is the kernel's recommended flexible sleep API. For a 100us delay, `fsleep()` will internally choose `usleep_range()` (since 100us falls in the 10us–20ms range where `usleep_range` is preferred), so the end result is essentially the same as v1 but without the caller needing to pick the range bounds.

```c
-	udelay(100);
+	fsleep(100);
```

Both replacements are in `write_reg8_bus8()`, which is clearly a sleepable context — it calls `par->fbtftops.write()` (an SPI transfer function) both before and after the delays.

**Minor observations:**
- The commit message and changelog are well-written and explain the rationale clearly.
- The `v2:` changelog below the `---` line properly documents what changed between versions.

**Reviewed-by worthy**: Yes, this is a straightforward and correct cleanup. No issues found.
